The first 31 sets which were for the ER mainly had four marker lights, one on the cab roof dome above the destination indicator, one above either buffer, and one centered inbetween those. Five sets (50370-4 + 56125-9) had a LMR-style 2-character route indicator in place of the lower centre light, and the two lower lights crudely plated over. When delivered these were not used at first and they were wound to the white section. As they could be illuminated, they were rumoured to be a new form of warning panel!
The LMR sets had only two lower marker lights, the roof dome was still formed to hold one but now only held a blanking plate, and the lower centre one was replaced by a 2-character route indicator. This was a rubber mounted one piece glazed unit, which became the standard on all later LMR Cravens units.
The LMR power twins and 3-car sets had the 2-character route indicator and only 2 marker lights, and no longer any provision for the top one. The design of the brake compartment in the DMBS was changed by repositioning the twin loading doors away from the rear of the vehicle to a point over the bogie centres, with the addition of an extra van window at the rear of the brake compartment. The centre cars were virtually identical to the DTC but without the cab. The DMS was also based entirely on the DTC but was of course powered.
These vehicles changed from batch two only by the route indicator which was split into two rubber mounted glazed sections, which became the standard on the ER & ScR sets.
The units that were intended for the M&GN lines in Lincolnshire and Norfolk, routes that were single lines under token operation. To avoid damage to the bodywork when the driver was catching the tablet when moving, when the tablet would swing back and hit the bodyside, a rubber pad was fitted between the cab doors and the first saloon window.
These kept the ER style twin glazed sections on the route indicators but reverted back to the original brake van layout of batch one.
This vehicle was the same as batch four.
The first image shows the LMR type, with one piece of glass covering both blinds, the second is the ER type, with each blind glazed separately.
Once the route indicators were no longer used there were a variety of random style found. Some had the blinds wound to white, some had two white dots on black in place of the blinds, some had them painted over in yellow, some were crudely plated over. In time many were properly plated over, and by 1982 all units left in service carried just the two marker lights.
