Western Cooper
Western Vanden Plas
Western etc. etc. etc. ........................ all long out of production - which is probably where this Off-Topic ought to be heading !
With that elliptical roof it's definitely not GER - and looks very GNR : No.42853 was a Howlden 45' Brake Composite of 1899 according to Nick Campling's Historic Carriage Drawings Vol.1.
In this case - with the axleboxes hidden - the buffers appeared to be 1923 type ................. but ........
With all due apologies - it IS a 1907 wagon after all ..... It's rather light for a 1923 and I can JUST see the top of wooden door bumpers !
Check the correct positioning for your loco : the arrow was normally between the nameplate and the crest/shield but some locos had the brackets higher up.
It's the reverse now - Hastings trains stop at Orpington but if I want to head to the Kent coast I have to change at Sevenoaks or Tonbridge ......... though the Journey Planners often suggest back-tracking to St.Pancreas and using HC1* !
*High Cost 1
Without reversal the West Drayton connection was only accessible from the east - so probably only of any use as a London bypass if several other options were unavailable.
Depends what they thought they were going to find - Royal Mail might know about high value 'conventional' cargoes but probably not if it was illicit substances posted by a rival gang !
What emergency transmission capabilities 60 years ago ? ...... I think radio contact equipment was added to the TPO coaches in response to the Great Robbery !
Little doubt they'd all have been in 'olive' by that time - and probably wouldn't have seen malachite green until after the war unless absolutely desperate for a repaint.
