Looks like Pakistan is having teething problems with new trains (well locos to be exact :P) built in China. In this case it caused a 4-6 hour delay to the Karachi-Lahore "Shalimar Express".

New locomotive ‘refuses to chug’

LAHORE: Failure of a new locomotive resulted in around four-hour stoppage of Lahore-bound Shalimar Express near Daharki on Monday, causing hardships for the passengers.

A source in the Pakistan Railways headquarters, Lahore, said since no other locomotive of 2000 HP capacity was available in Karachi, the authorities dispatched two locomotives of 1500 HP capacity which reached Daharki after three hours and 50 minutes. The 'substitute' locomotives (Nos 4901 and 4914) took six extra hours to bring the train to Lahore.

A mechanical engineer of railways told Dawn that during initial operation, problems did surface.

"Any new locomotive introduced for the first time in broad gauge network of the Pakistan Railways, where heat and dust become very prominent in summer, do get some teething troubles that need adjustments.

There had been much more teething problems whenever new locomotives were introduced on the PR network; the General Motors (USA) and Hanshel (Germany) crankshaft was broken, for GE (USA) cylinder piston were burst and for Hitachi (Japan) locomotives bogies were bent out," recalled the engineer.

A railways spokesman in its headquarters in Lahore said the Chinese locomotive developed a minor electric fault on the fourth day of its induction into the Pakistan Railways fleet.

"The locomotives are under warranty and Chinese engineers will remove the electric fault," said the spokesman.

While this link says it was a computer fault:
Meanwhile, a spokesman of Pakistan Railway said that there was a fault in engine’s computerized system.

The spokesman said that local technicians were not trained to use computer technology.

This one sounds more like a fault with the people who wrote the cheque, not with the builders of the locomotives.

Properly-specified locomotives and wagons built in China have been performing quite well in Australia for some time now, they are definitely far better than the point that US-sourced equipment was 25 years ago.

Replacing good old fashioned mechanical locomotives that could be fixed with a good toolbox with complex electronic machines without taking the time to train up the maintenance staff is always going to lead to problems.

Perhaps they did not pay for enough testing - there are plenty of hot and dusty areas in China, but probably not broad gauge track.

The performance of electronic modules can be tested with the locos running on whatever gauge is most convenient!

Swapping bogies on a loco is simple stuff, here in South Australia alone we have a couple of diesel-electric classes which are currently in service on 1067mm Cape Gauge, 1435mm Standard Gauge and 1600mm Victorian/Irish Gauge.
