The use of a telephoto lens here helps demonstrate how bad sagging on long wheelbase vehicles could be, particularly on the 3rd vehicle.

A/E

Although both batches of Class 126 were white circle, the two were not originally compatible. The 1956 batch had 'A' type controls, and it's white circle system was basically yellow diamond (as the Derby/Met Camm Lightweights) with no through air pipe. The 1959 batch had the now standard 'L' type controls, and its white circle system was basically blue square with no through air pipe. Some rewiring had to be done to allow the cars to work together. It is suspected that buckeye couplings and Pullman gangways had as much influence in the choice of a different coupling code for this Class. Not all trailers were declassified to TSLs, the buffets being withdrawn many years earlier. This batch worked Glasgow to Ayr & Stranraer services from new, allocated to Ayr. Unusually, the TCKs and TFs were both given the same class - 189, while TFs that survived from the 1st batch were given their own class - 188. There is no mention of the Ayrshire units having the guard's van at the inner end, unlike most E&G cars. The underframe layout differed considerably between the two batches, and the Ayrshires had jumpers on the full-cab ends etc.

More anachronistic references to "standard" class.

The 3 types of vehicles were slightly different lengths. The Class 127s were built with the blue square multiple control, and therefore were compatible with most other new DMUs. When coupled to gearbox cars, drivers had to adapt their driving technique when driving from the hydraulic cars. Driver error with this led to many incidents, and after a bad fire in 1968 it was decided to rename the Class 127 code to Red Triangle. There was no rewiring done, and they would have been in no way compatible with the early Red Triangle units, withdrawn a few years previously. The lack of 1st Class accommodation was unlikely to have anything to do with the lack of toilets in other vehicles, as the 1st Class would be in the vehicle with the toilets as on other similar sets. A power car is also preserved on the Llangollen Railway, running with a Class 105 DTC. The guards vans were smaller than the 116s etc. but there were two per unit (also applies to Class 115s).

The blue square code is correct (this is also evident in the previous picture).

M51630 is a DMBS.

The 3rd vehicle has a light grey roof.

The DMBS were built with 78 seats, a swing door allowing access between saloons later fitted reduced this to 76.

For many years the 127s were required to carry tail lamps, as did many DMUs which had lamps fitted. This was apparently due to a union disagreement over the use of the red lamps.

The parcel twins were only ever BR blue, no other shade of blue was used.

The cab driving windows were also to the side on the WR vehicles, the centre window being separated from the cab by a bulkhead. Not all Swindon Inter-City units with side driving cabs had Leyland Albion engines!

The first van is not a standard GUV but a bogie van of GWR design, possibly a BG (note the curved roof end).

Presumably should read 1988 instead of 1998.

Each side had two single slam doors for the cabs, two similar doors paired with windowless doors in the parcels area while at the guards van end there was an inward-opening door beside the third windowless door.

The oil lamp was carried as the fitted lights were all white.

A/E?

Would the jumper receptacles be white? This was the usual colour, and would be to try and avoid jumpers being "crossed" when fitting.

221

bottom

A

The receptacle colour change in the above picture obviously didn't work, so one jumper was permanently fitted on each corner, with a dummy socket. This meant that they could not be multied wrongly.

Only one B4 bogie was fitted, the other end retained the original.

Confusion reigns regarding the power equipment of the vehicles adjacent to the driving motor brakes!
