I always think the 'Janus' is a nice looking diesel shunter.
This is probably a bit of a 'stable door shut after the horse has bolted moment' after reading about the motor/gearbox arrangement.
Is it worth considering an alternative using a smaller gearbox, driving the centre axle and slinging the motor lower between the frames?
It may mean having a false floor in the cab or hiding any protrusion with the control stand.
It's something I did with a Connoisseur 0-4-0 'Nellie' tank engine using a SDMP/Finney7 Power gearbox and Canon 1833 motor. I'll program the decoder to give me the slow speed control.
