No doubt patrons of a voluminous physique would find them testing.

Is the Kalyan WDM2 at the other end or in the middle of the rake. I have always seen this train with the loco in the middle and driving cabs at eah end. Some years back, the locos used to have a livery similar to the rake, but now it seems all have been painted to KYN standard maroon-blue.

Many thanks for the pics Raghu. The 2 coach HHPDEMU is also the most powerful passenger on the IR with 1400 HP for the puny load...

Some conventional Air-brake liveried coaches have sneaked into the formation. No wonder Alok saw a coach from this train with the Nagpur-Indore Express!!

I must clarify, both DHMUs and DEMUs are a type of DMU. The one in my picture is a DEMU.

I think its a Diesel Multiple Unit. I read somewhere that a Diesel Hyradulic Multiple Unit has only 3 coaches. This one has more than just 3.

This is what I think the difference is (someone can feel free to correct me, I am neither mechanical engineer nor an electrical engineer)
A DHMU is like a large car that uses automatic transmission. Power is hydraulically transmitted to the wheels. DMUs on the other hand run a diesel generator that produces electricty which then runs traction motors.
I guess its less cumbersome to handle electricity (which can be easily controlled by thyristors etc for speed control), than it is to manage raw mechanical power, so DEMUs are more popular.

Is it a DMU or a DHMU? What's the difference between the 2?

That handle with the white Head is very similar to the handles found in the Mumbai EMU ( AC / DC ). I wonder if a track inspection Driver is allowed to drive bigger systems like EMU or WAP serries ?

Looks like a single unit Railbus type DEMU. But I am sure as experts commented this week a couple of more dummy coaches and powered coaches can be added to extend the rake to 10 to 16 as and when the need arises due to the volume of Passengers. Good Photo for the appetite of Rail Fans.

Nice colorful pic....fantastic greenery.
