Whilst converting my DMU Gordon Hopkins was demonstrating his class 508
emu at MERG. he kindly supplied two sets of his pcb multipole couplings
to help with running the electrics through the train.
These provide 7 wires through the coupling and hold just by the
friction of the 7 pins in their sockets. This has proved to be
perfectly satisfactory in operation and gives effectively a rigid bar
These pins provide: Left and Right rail busbars, Lighting positive, headcode, tail light and interior lights and one spare wire.
The photos show various views of the installation, orientation is
F-M, F-M on the 3 car set so it can be assembled as a 2 car set if
required. Pickups are from all wheels of the powered car and from the
two wheels of one bogie on each side on each trailer, so 8 wheels each
side in total. Click on the image to enlarge.
