REVERSE ENGINEERING OF A ‘TRAIN AUTO-COUPLER’ TEST BOX, FOR A 320 CLASS LOCOMOTIVE

auto coupler testbox reverse engineering 320 class locamotive
Our brief was to reverse engineer a ‘Train Auto-Coupler’ Test Box, for a 320 Class Locomotive, there was only one in existence; it was manufactured a long time ago by Alstom, and there were no drawings available.
The Auto-coupler Test unit is used to Test the wiring and the functionality of the controls from the Drivers Seat to the Auto-coupler, which connects the Loco to the next Train Carriage.
We managed to do this and create a drawing package so that we could manufacture more in the future.
The customer has emailed with the message below, he was a happy chappy.
“Good Afternoon Gents
I’ve just been sorting out some paperwork and came across a quote for our coupler test box.  I then thought to myself that I never thanked you properly.
Thank you very much.  We tested our unit last month and had no problems with the test box at all.  I really appreciate all the work you did and don’t know many, if any, companies who would have done such a good job.
Kind Regards”
