Wickham Green too

OK - AVERAGE case then : Measure the bridge & take photos .... road resurfaced half way through regular inspection period leaves half regular inspection period for the bridge to get struck.

Rustic is best !

Measure the bridge & take photos .... road resurfaced next day leaves regular inspection period for the bridge to get struck.

21T wagons tended to stay on the flows that 20/21T wagons had been on pre-war - and Stephenson Clarke had a lot of them ...... possibly a few different 'owners' mixed in at the far end of this train.

.... and how often would you expect them to send out a guy with a tape measure* to check that some other authority hasn't moved the goalposts without telling them ? * Metaphorical tape measure nowadays - a laser device wouldn't involve too long a road closure between vehicles.

I note you are calling for seats* rather than benches** .......... * implying comfy ** implying current standard

At least two Whitcombs ( similar but earlier ) were at Longmoor 'til the late fifties - they certainly count as having operated in GB..

... which I feel was 'designed' as above. ( Whatever its origin, it's certainly a rebuild and NOT a new, locally-built, body as the main structural diagonals have been cut through for the windows.)

Clearly whoever 'designed' the Devonport van carriage had an end elevation of a Midland vehicle and side view of an LSWR one to hand - and probably the 9'9'' wb chassis of a 15T mineral wagon !

They were popular for hanging on the back of steam excursions at one time - is that still the case ?

A simple matter now they've got FAR better Southern bogies in their portfolio. Mentioned before, I'm sure, but a decent Brighton brake van would be welcome - especially with a K class on the horizon ............. come to think of it, a C2X would be even more welcome - though I'm sure that's cropped up before too.

According to Mike King, in his Southern Coaches Survey ( 2019 ), it was considered that the ex-LCDR six-wheelers were some of the best for comfort so other vehicles were kit-bashed into electric units instead ................ mind you, I suspect other 'new' electric units were rebuilt from LCDR four-wheelers - retaining little, if anything, other than the door furniture !

... so an LSWR dia.1410 - fitted with screw couplings - would have fitted the bill perfectly. ( Other oil-boxed lwb vans were available )

Can't help wondering why the second train was still on the move if the first wasn't proven to have stopped in the loop.

Can't help wondering why the WD would have wanted their 'own' design rather than adopting something that already existed - it's only a box on wheels after all !
