The Ayjay Models 4 SUB kit has arrived from Radley Models. Oddly, it came with four trailer bogies and four motor bogies. I contacted Phil Radley and he immediately offered to send out the two missing trailer bogies. I also asked if he wished the extra motor bogies returned but, as yet, he hasn't replied to that. Excellent service, as always, from Phil.

With this kit, I am using the Hornby 2 BIL motor chassis but will have to use the Ayjay resin chassis/underframes for the remaining three coaches.

I have cut off the buffer beams from one of the DMBS bodies and sat it loosely on the Hornby underframe.

The semi-saloon seating unit will have to be cut to suit the Hornby chassis configuration, losing one seating bay in the process to clear the motor housing.

I have not yet chosen a unit number but am probably going to select one from the 4355 to 4363 group as these had two 10-compartment trailers to match what was supplied in the kit (edit: these units may have had compartment motors too, unlike the kit). That also means I will retain the foot steps over the front buffers and add handrails above and either side of the front at windscreen level (similar to the 'Tin' HAL).

This also shows the interesting contrast in front ends for what were otherwise almost identical body shells for the DMBS vehicles in the 2 HAP and the 4 SUB. The roof details also differ somewhat.

It also shows that I have thinned the lower roof edge gutter on the HAP to improve the appearance.
