By popular demand (well – one or two requests), here’s a video of CNR 15815 – my recently-completed gas electric – running as M233 to Port Rowan:
(You may also view this movie directly on YouTube, where you may be able to watch it in larger formats)
The decoder is an ESU/Loksound Select board, loaded with an early GE diesel prime mover – the kind used in the 44-Tonner. While I’m sure a gas-electric sounds different – in the same way that a gasoline-powered automobile sounds different from a diesel automobile – I’m happy with this unit’s “voice”. It burbles appropriately to my ear – and it should be noted that most of the CNR’s self-propelled passenger carriers were diesel-electrics (or “oil-electrics” as the railway called them).
If ESU ever produces a gas-electric sound file, I can simply reload it. Or I can swap out this decoder for one from QSI, which does offer a gas-electric.
The sound escapes from the model primarily through the windows in the baggage doors, which do not have glass installed for this reason.
I’ve reduced the maximum voltage (CV 5) to about half of the available range, with a suitable adjustment to the mid-range voltage (CV 6). I’ve also added a fair bit of momentum to both acceleration (CV 3) and deceleration (CV 4). This unit runs very smoothly at realistic speeds.
Enjoy if you watch the movie, which will take less time than it did to pop the corn in the microwave…
