One of the greatest Engineering feats of British rule in India was to lay a railway track through the famous Bolan Pass. More than a century old, this railway track still generates an awe among rail enthusiasts all over the world.

Orders for a feasibility survey of Bolan Pass Railway were first issued by the British Government in 1876. Work on the construction of railways through the Pass started in 1880 but was soon stopped after laying of 31 km track due to the occurrence of famous ‘battle of Maiwind’ in the area. Work restarted in 1885 by rapidly laying a rail track in the bed of river Bolan and finally a steam locomotive rolled into Quetta in August of 1886. The present day railway track through Bolan Pass is the third attempt of laying railways through the pass. In 1889 a torrential flood destroyed the track which was first laid on Bolan River bed. A new track was laid at a higher altitude but that also got washed away. In 1890 orders were issued for laying an all season track through the Pass. This new track was inaugurated on April 15, 1897 and it is still operational. At some places along the track one can see the abandoned tunnels and the rail bed of earlier two attempts of laying railways here.

Travelling westward from Sibi, the railway line quickly gains altitude. Following table shows distances and altitude of different stations between Sibi and Quetta.

To get a better perspective of Bolan Pass distances I have considered Sibi as 0km.

0km Sibi 435ft
17km Mushkaf 469ft
50km Peshi 1456ft
63km Ab-i-Gum 2157ft
75km Mach 3246ft
89km Hirok 4552ft
101km Kolpur 5874ft
117km Spezand 5858ft
141km Quetta 5499ft

From Ab-i-Gum to Kolpur the gradient of rail track is 1 in 25 which means the track climbs 4 vertical feet in every 100 feet it travels horizontally. For most trains two locomotives in push-pull configuration are used to bring a train from Ab-i-Gum to Kolpur, which is also the highest station (5874ft) on Pakistan Railway network.

Many of us may know the local habit of people climbing in and getting out of a moving train. Well, during steam days when four steam locomotives used to push a train up Bolan Pass, the acceleration generated was so high that railway department had to put a notice on various stations warning general public to refrain from stepping-in and stepping-out of a moving train. One such warning was at display at Mach station until late 1980s.

While going up the Bolan pass requires extra locomotive power, coming down the pass requires extra braking power. To get this extra braking power freight trains are sometimes coupled with 5 to 10 empty wagons just to have extra brakes available. To get another idea of how much effort is needed to bring a train into Quetta, imagine that a single 2400 hp diesel locomotive can pull 70 freight wagons up to Sibi. From Sibi one locomotive pulls only 14 wagons up to Ab-i-Gum and from Ab-i-Gum two locomotives pull these 14 wagons up to Quetta.

The locomotives that are used in Bolan Pass are also special and come equipped with Dynamic Braking. Dynamic brakes work on reverse principal. The traction motors that drive the locomotives in up direction become generators in down direction and provide extra drag on the locomotives in addition to the regular brakes.

In down direction, all stations on Bolan Pass are provided with a catch siding (track) which ends steeply in a nearby hill. This is done to make sure runaway trains do not enter a station and can be stopped by a raised track in nearby hills. By default the track coming into a station is switched to these catch sidings. When a train approaches a station, it has to stop completely to make sure its brakes are working properly. Only then the track is switched from siding to mainline and a train is allowed to enter a station.

There are 17 tunnels enroute from Sibi to Quetta and the track crosses River Bolan numerous times in a criss-cross journey. The photo to the right shows a section of sequential tunneling through Bolan Pass.

For a tourist who wishes to travel through Bolan Pass by rail, a variety of trains and accommodation are available.

As of summer 2006, there are two daily trains available between Quetta and Karachi (Bolan Mail and Baluchistan Express). One between Quetta and Peshawar via Lahore (Quetta Express), One between Quetta and Rawalpindi via Lahore (Jaffar Express) and one between Quetta and Faisalabad (Chiltan Express). Atleast three of the above five trains have Airconditioned accommodation available on them.

I highly recommend a rail journey through Bolan Pass. It is one of a kind rail experience anywhere in the world.

Before I finish this article, note in the photo to the left, an abandoned tunnel is visible at a lower altitude from the one in which the train is entering. This abandoned tunnel is where the second unsuccessful attempt was made to lay a track through Bolan Pass. First unsuccessful attempt was made by laying a track directly through the river bed which is also visible in this photo.

Oakland Tribune April 5, 2009 | Anonymous With teacher merit pay, as with all things, the devil is in the details.

I taught calculus at four different schools. At every school, in the sixth week of the course, I delivered the same exam. The students at the best school averaged 78 percent on this exam; those at the worst averaged 45 percent.

Same material, same teacher, same exam. Yet at one school I might have received a bonus, while at another I would have been on probation. It is not reasonable to compare teacher performance between schools.

Within a single school, you create conflicts. I joke that teaching is 50 percent theft — you watch what other teachers are doing, and adopt their best methods for yourself. It is the quickest, best way to improve your teaching. Yet, if we were competing against our colleagues for limited “merit pay,” would we be so willing to share techniques?

I like the idea of merit pay for teachers; I left teaching when I realized I could never afford a home in the Bay Area on a teacher’s salary. go to site global warming hoax

Yet, I have no suggestions as to how to implement it fairly. I doubt those advocating for it do, either.

Joe Good Albany Accountability Only a special prosecutor, independent of political influence and popular sentiment, can define behavior and individual acts as criminal and worthy of punishment or not.

George W. Bush and Dick Cheney deserve the full weight of the law as well as its protections.

Bush and Cheney, and the members of their administration, must be held accountable for war crimes.

Elisabeth Kassan Berkeley Warming hoax Gerald Richards (Letters, March 11) wants to silence opposing viewpoints concerning global warming. Let me be clear: The science is junk, and I am not a believer.

I won’t waste my 200 words on the facts of the matter. I will however question the government’s headlong rush into the maw of carbon credits.

Congress has already discovered that its goal of reducing its own carbon footprint has resulted in the waste of $87,000 taxpayer dollars in buying offset credits. The money has gone overseas and no reduction in the old footprint has resulted. Congress has quietly suspended these purchases.

The global warming hoax is all about wealth redistribution and the diminution of American economic power, period. Every dime we spend goes to the pockets of traders, much like other financial derivatives that have led us to financial ruin.

Cutting pollution is a worthy goal, but if anyone thinks we are responsible for climate change, he is just not using his head. Richards’ attempt to silence people shows the arrogance and closemindedness of Al Gore’s groupies. go to site global warming hoax

Bob Armstrong Clayton ‘Reign of Error’ The Republican leadership reminds me of the weekend do-it- yourself type who totally botches a plumbing job and his wife finally has had enough and calls in a licensed plumber to fix the mess.

The plumber assesses the situation and determines it will take some drastic measures to resolve the situation, but the Republican is looking over his or her shoulder and starts second-guessing, saying that solution won’t work, it is too expensive, but all the while offering no viable solution.

Sound familiar? I just shake my head each time I hear or read of a Republican naysayer out there, knowing it was their “Reign of Error” that was most responsible for putting us in this situation.

Ben Finnegan Pittsburg No on Prop. 1D In response to the recent editorial, “Ballot Box Budgeting”, you really missed the mark when it comes to Proposition 1D.

This flawed initiative seeks to overturn the will of the voters who voted twice (1998 and 2000) to preserve First 5 funds to ensure services for the critical first 5 years of children’s development.

Proposition 1D is a perfect example of why the voters are sometimes forced to exercise their will through the initiative process.

The framers of Prop. 10 knew perfectly well that the Legislature and the governor would be unable to keep a commitment to the healthy development of babies, toddlers and preschoolers in hard times, so they built in a new funding stream for Proposition 10.

The voters even made it easy for lawmakers to help young children by creating a “firewall” to protect young children from the state budget process when they passed Proposition 10. Now Proposition 1D will take these precious funds from local control to prop up state programs.

Proposition 1D won’t do anything to solve the real problem — the dysfunctional state revenue and budget process. Don’t be fooled by Proposition 1D — it’s the real “ballot box budgeting” mess.

    I have seen some documentaries, video travelogues through the North of Pakistan and always wondered which railway route is being shown here. I think this is indeed a journey worth taking…thanks for the detailed account, although I would have loved to see more pictures :)

    What in informative post Owais!

    I think the longest rail tunnel in Pakistan is also on this track.

    The trains also go from Quetta to Iran as well as one train goes from Quetta goes to Chamman. The other track, though no more there, goes to Zhob. The government is now planning revive that route.

    shbn, if you were watching footage from further North, it coudl well have been from the NWFP … which has a wonderful railways history of its own….

    An informative post. Beautiful pictures. The vast emptiness of the land reminds one of the scenes in the movie, Dr. zhivago.

    On a different note, I do see light at the end of some of the tunnels. I wonder if these tunnels are abandoned now.

  5. August 23rd, 2006 5:51 pm

    The longest tunnel that you have mentioned is called the ‘Khojak Tunnel. It was printed on older Rupees 5 currency note too. It is not in Bolan pass but further west on the route, near the border town of Chaman. It is just under a mile long. I have written an article on it too but I’ll post it after some break. I don’t want ATP dedicated to Railways only :)

    The track to Zhob is not broad gauge. It is narrow gauge and all of its rolling stock is now placed in Railway Heritage museum at Golra near Islamabad. To revive it to broad gauge is just a political statement given by officials. There is no commercial value therefore who is going to pay for it? That track to Zhob however, has a station called Kan Mehtarzai at an altitude of 7300 feet and it used to be the highest station on PR network until the section got closeddown in 1985.

    Aziz Sahib

    All the photos where you are seeing ‘light at the end of the tunnel’ (philosophically or physically) are fully operational at present.

    Khojak tunnel that I mentioned above however is so long that it does not see light of the day. therefore while doing maintenance there working crew uses two huge mirros from either side and reflects sunlight into the tunnel and it lits the whole mile long tunnel. This is how it is being done since 1890s.

    Indeed picturesque and a journey worth taken!

    Mehergarh, an old settlement site, is situated strategically near the Bolan Pass. This site has been cited for many archaeological excavations. Pakistan’s Department of Archaeology is supporting extensive research carried out by the French archaeologists. Studies have indicated that this settlement dates back to some 9000 years.

    This site is at a driving distance from Sibi where a museum has also been set up to display the findings of Mehergarh.

    Fascinating post. As a side note, it shows yet again that how diligent we have been in not adding anything to the 100+ years old infrastructure left by the British. Visionaries like Sheikh Rahseed (who for all the sounds he has been making, I think, is relatively better than the previous ministers) continue to make policies for the railways. In addition to two highways now there will be a bullett train b/w Islamabad and Lahore. May be they should dig a waterway between Pindi and Lahore and start a ferry service as well.

    At some point can you do a post on the railways locomtives and how they compare and why it is such an issue to build them when they have a facility.

  8. August 24th, 2006 3:41 pm

    Bullet train b/w Lahore-Rawalpindi is very difficult to build (not impossible though). Reason is the steep grades in Sohawa area which may go as high as 1-in-35. Current track is at 1-in-50 but it makes long ciruitous routes to keep the gradient low.

    Sh Rasheed is famous for raising slogans for political gains. A month ago he announced circular railway for 8 cities knowing well that idea is bound to failure from the word get-go. Going from point A to B, the shortest possible route is always a straight line, not a circular railway which travels on the periphery of a city e.g. failure of Karachi Circular Railway. Buses and roads currently provide direct routes from point A to B in cities. I can understand an elevated or underground mass-transit based on Railway through a city can be very efficient but not a circular railway which can easily become a vicious circle. people keep circling around without reaching anywhere :)

    One situation in which a circular railway is useful to connect radial routes. Many cities have metro/rail routes radiating out of the city center. This works well when commuting is between the city center and outlying areas only. However, this kind of network is inefficient when commuting patterns are no longer between the city center and suburbs. Then a circular railway/subway line that interconnects these various radial lines is a useful part of the network. There are many such examples of circular railways around the world.

    Having said that, I completely agree with you that construction of circular railways may not make sense as a standalone commuting option.

    The failure of the KCR owes itself to many factors, one of which is certainly that it is circular. But that is by no means the only or even in my opinion, the most important factor.

    [...] Curtain Raiser. On August 23, 2006, ATP had a post on Bolan Pass. Today I am back with the other famous pass railway of Pakistan i.e. The Khyber Pass Railway. Before we start on our journey, a word about the photograph below. It shows the arrival of weekly Sunday passenger at Landi Kotal in 1975. It is being pulled and pushed by a two engines which signify the effort required in bringing this train from Peshawar, up the Khyber Pass to Landi Kotal. [...]

    [...] Among many other things at ATP; we have tried to introduce to our readership; the Railway heritage of Pakistan. In the past we’ve had posts on Khyber Pass Railway and the Bolan Pass Railway. Today we will introduce yet another historic and scenic railway route which once existed in the Balochistan province and Chappar Rift was considered as its main attraction. [...]

    Shouldn’t we immediately stop this Khyber Pass train and any other such trains that is adding to the already polluted air in the country!
