Class 43s and DVTs

[TrainfanBen]

Hello, I am new to the forum. Ive seen some interesting threads and thought it was time to say hello

I would be interested to find out what is the difference between a class 43 and an MK3 DVT.

If there has already been a thread regarding this, sending me the link would be fantastic


Thanks

Welcome to the forum

A Mk3 DVT is basically a Mk3 coach with a driving cab at one end, and the interior is used for storing things like bikes.

A class 43 HST powercar contains a diesel engine, electric traction motors, and all sorts of other stuff necessary to provide power to haul a train.

It's a bit like the difference between a donkey and a cart.

Although, for the record, while Class 43s haul Mark 3 coaches - the Mark 3 coaches that DVTs are worked are designated Mark 3A and have different electrical braking and electrical systems, as well as buffers.

Welcome onboard!

 

[TrainfanBen]

Thanks for that.

And there was me thinking they redesigned the 43s as DVTs

Not too far off as a small number of 43s were used as pseudo-DVTs for a while when the 91s were being introduced, and there are a few threads about that somewhere on here.

They had to be switched on to provide ETH, but with engines idling. This was not good for engines, so they then decided to have the 43 powering. This gave around 8,500hp for 8 coaches therefore some very impressive timings were achieved.

All of the former pseudo DVTs, identifiable today by their buffers (and the fact they are all operated by Grand Central) can still be found on the ECML.

Surprisingly the 91s have not since the 90s hauled anything but mark IVs.

Not all, two buffered power cars are operated by Network Rail for the New Measurement Train.

You learn something new everyday on the forum

Ive seen a pic of a 91 hauling a rake of mk 1s.

I'm guessing the implication is during normal usage, rather than test trains etc.

In the early days they hauled all sorts on test trains.

They were designed for both passenger and freight work.

It's hardly surprising that they are only normally seen on one sort of work, considering that the entire (small) fleet is run by one operator, and they're solely in the long distance passenger market!

They are still known on the odd unusual working. Trains of barrier vehicles, or coaches to works and the like.

Yeah compared to some countries in europe where you will get the same class of train or carriage across the network.

91's have been known to 'rescue' HSTs in recent years

test train or service train- consist of mrk2s, including a brake coach from the charter fleet

91007 hauls the 15:45 York - King's Cross awary from York on 20th May 1990
Given that was a Sunday it would probably be charter or utilising the Peterborough commuter stock
