Help needed please with some locations Hastings Demu class 6S

I have recently been given a very large amount of 1950’s Steam loco photos by Marcus Pettman
Also included were some photos of the Hastings DEMU’s class 6S

including this photo of 4 units on shed unknown location any help please?

The two unknowns look like Tunbridge Wells 1003 is going up and 1007 down

The unknown shed might be St Lenards. The lockation is not Ore as that had third rail for the electrics to Brighton. The running lines do have juice rails so clues sugest St L.

 

Thanks Dave, your observations have been confirmed by others on the SEMG group

Neil,
It would be interesting to find a pic of a Hastings unit when diverted via Redhill and New Cross Gate. It was a divertionary route when the line via Sevenoaks was closed. I well remember the discussion I had with the guard who said I could not use my season ticket on the service (Staplehurst to London SR)

 

Sorry I do not have any at those locations

Neil

 

Does anyone recall why the first few units were built on short underframes (6S) and not on long underframes (as 6L) from the start?

May I digress a little to share an anecdote. Many diesel engines are left running all day and many stations have a haze of diesel fumes. This was not the case at Cannon St or Charring Cross. The Hastings diesels were habitually shut down to avoid fumes. One day I saw Johny Baker strolling down the platform at Cannon St. As well as a main line driver he was a steam driver at KESR which is where I knew him from. It was less than 10 minutes to train time and all was quiet Just before the off bub bub bubber bubber roar repeated down the train as the 4 engines started. The last engine had hardly started when the guard gave the RA and we were off , first stop Tonbridge. This truly was having faith in your kit.

of the Hastings DEMU’s class 6B/class 201
These photos show the units from the 70’s onwards including railtours

Not sure about this combination

Neil,
AFAIK the multiple unit connectiions were the same on diesel and electrics which had the EP brake plus 73 and bagpipe 33 locos. The odd combination would work. The only glitch likely to raise its head with odd combinations is the crossover of forward and reverse control circuits. Diferent units did it in diferent places. CEP for example was in a trailer car. HAP in the DTC. There is a story that the first CEP refurbished at Swindon when put on the juice for the first time would mot move when power was applied although the motors were taking curent. Swindon had forgotten the control circuit swap in the rewire

 

Because the short underframes were ordered before the decision to dieselise was taken.

Basically the original idea BR had was to replace the pre WW2 Maunsell rolling stock with something more modern - but due to the constraints at Charing Cross the length needed to be kept down as otherwise a 12 coach train plus a schools loco would not fit in the platforms. Short underframes were therefore designed and started to be ordered from the works before publication of the Modernisation plan meant a rethink happened. By going down the DEMU route, the SR realised they could get rid of the need to take a potential locomotive into account when considering train lengths and it could make the individual vehicles within what were to become the Hastings sets longer. Hence later builds got longer underframes compared to the initial batch.

 

Thank you - most interesting. Given the length consumed by the engine compartments they ended up with the equivalent of only 10 carriages anyway!

 

The physical connectors were the same for EMUs and DEMUs but the pin assignments were different (eg: DEMUs had seven power levels, so needed 3 wires, while EMUs had four power levels so could use 2 wires).

My dad was a guard on the KESR, knew Johnny Baker well and also happened to commute from Wadhurst. Many's the time he dived into the engine compartment of a Hastings unit en route to make the cab appear rather, um, emptier than it was...
