I was watching a few of those wonderful videos from India and Pakistan and noticed an interesting trend. The trains are, of course, amazingly lengthy. The other thing I noticed is that most electric trains have one or two power cars (generator cars) on the.
What's the reason? I can guess a few, like consist length for cabling, lack of HEP on the engine, or perhaps reserving all the prime mover's energy for traction, or maybe just plain neglect.
What do you think?
PROBABLY BECAUSE THE POWER FOR LIGHT AND HEAT AND AIRCONDITIONING IF ANY IS NOT COMPATIBLE WITH TRACTION POWER AND THE LOCOMOTIVES DO NOT HAVE CONVERSION EQUIPMENT
