    VCT has the former ID of this coach as 4378 whereas my lists have 4377 - anyone any idea which is correct please?

    Is'nt it S1000S ?

    It is/was S1000S, but it was constructed on the underframe of one of the two Mk1 TSOs referred to above which were involved in the 1957 Lewisham disaster.

    I've dug out Peter Tatlow's book on the Lewisham accident, but it isn't absolutely clear - appendix 2 is the key section. S4377 and S4378 were both involved in the accident, being the 2nd and 3rd coaches in the Ramsgate train, both ending up underneath the collapsed flyover. In the remarks column, it states 4377 was cut up on site whereas 4378's frame was salvaged. However the footnote states that it was 4377's undeframe that was subsequently re-used!

    Parkin states 4377 was used.

    I seem to recall reading somewhere that some research was done recently that strongly suggested S1000S/DS70200 was built on 4378 not 4377 as officially documented - frustratingly I cannot find the reference.

    The West Somerset Railway states it was 4378 and specifically not 4377:

    A somewhat macabre history for this vehicle then.

    Thanks for the replies - we also got some more info posted on the Yahoogroup mailing list a few days ago...

    I never realised that this coach was built upon a Mk 1 underframe.

    Why then was it numbered S 1000 S ? Normally an "S" suffix would indicate a coach of Southern Railway origin.

    I think it was numbered with an S suffix because it was non-standard (having the fibreglass body). My understanding is that a suffix letter did not automatically mean a vehicle of pre-nationalisation design, but rather indicated a non-standard nature which meant that maintenance (particlularly heavy maintenance and the provision of spare parts) was the responsibility of the specified region.

    Various examples support this conjecture: the Eastern Region double deck car carrying vans were E suffix; the Manchester-Hadfield class 506 emus carried an M suffix (though of LNER design) as all maintenance was done by Reddish depot; the Isle of Wight tube stock, though of Underground origin were suffixed S, etc.
