What does ‘microprocessor control’ for a locomotive mean?
June 20, 2019

'Microprocessor control' can mean a few different things. A few of the newer electric locomotive models such as the WAP-5 or WAG-9 with complex 3-phase AC drives have circuitry and equipment controlled by microprocessors. In these, the microprocessor or computerized control is an integral part of the locomotives' design. Some of the newer diesel

How are locomotives ‘run in’ to prepare them for service?
June 20, 2019

New locomotives are run in for a period of time after being commissioned from the factory in order to shake out any possible initial manufacturing defects and for all the components to settle into normal wear and usage patterns. In order to give the loco a reasonable load and much starting and stopping opportunities, usually the new loco is run in

What driver vigilance or driver alertness systems are used by IR in its locomotives?
June 20, 2019

Several loco classes have speed limiters with buzzers that go off when the prescribed speed is exceeded. In some cases these may also result in the application of brakes. Some WAP-4 locos have the buzzer system and it is set for a speed of 130km/h although they are capable of going faster, while a few WAM-4 locos have it at 110km/h (although not

I’ve heard that some locos have ‘cruise control’. What does this mean?
June 20, 2019

Some locomotive classes such as the WAP-5 and WAP-7, as well as the WAG-9, have controls in the cab that can 'lock' the train to travel at a certain speed (the speed at the time the control or button is set). The button is known as the 'BPCS' button. The computerized loco controls then manage the tractive effort and braking effort and attempt to

Why do trains sometimes feel like they are momentarily rolling backwards (or forwards) just after coming to a halt?
June 20, 2019

Today, almost all braking of trains moving at speed is done using the train brake system which activates (air) brakes along the length of the entire rake. The loco brake system is not used for bringing the train to a halt. However, as soon as the train comes to a halt, most drivers switch immediately to the loco brake system to hold the train at a

June 20, 2019

Where can I find locomotives from India that have been preserved or restored outside India? During the World Wars, many Indian locomotives were transferred to the middle East, Africa, and elsewhere to support British military efforts. Most of these locomotives of course do not survive now and may be difficult to trace. Details of these wartime
