Smoke for a narrow gauge railway loco

[Steve_D]

So a 2 foot gauge railway with a loco that looks like a steam loco but is in fact powered by a Ford transit diesel engine. (No hurtful comments, it's very sensitive).

We are looking to try and make it smoke.
Anybody seen it done or have any suggestions how we could do it. Non polluting would be good but I suspect that may not be possible.

Thanks
Steve

A DJ smoke machine or plumb in a CO2 fire extinguisher to a valve that you can control so it can puff little but often.

The DJ smoke machine looks spot on. Thanks

I thought they were dry ice so not really suitable but these use 'fog liquid' which is water and glycerin so quite safe.

If you could link a rotary valve cum plenum chamber to the axle, you may be able get the speed related 'puff puff' effect of a steam driven locomotive.

It’s a transit engine…and it’s not already smoking???

Model aircraft smoke systems inject baby oil into the exhaust. Simple pressurised sealed tank running off exhaust pressure pumps the oil into the exhaust and does the job.
