Thompson L1 and electric lights

Post by barnowl »

Hi
I have a Hornby Thompson class L1 no.9001.
I am in the process of fitting a sound decoder and also lights.
They have electric lights fitted front and rear.
I am in need of some advice as to how the electicity for these lights was generated.
A dynamo comes to mind. Or a battery/generator.
The reason being is that I want to add any additional sound effects when the lights come on.
i.e. sound of a generator etc.
Also when the loco was stationary how would such a device be powered?
Any help would be great.

Ay up!

The L1s had a steam turbo-genny beside the smokebox.
If I ain't here, I'm in Bilston, scoffing decent chips at last!!!!

Don't have one of the Stone's generator on on L1 but this pohto shows one attached to K1 2005. As far I know the layout was the same on the L1

Thanks for that.
I have found one on the side of the model.
Would I be correct in thinking that as the electical load increased then sound of the genny would change accordinally?

I don't think that is a sound that you need to be concerned with. Unlike say a Westinghouse pump, I cannot remember hearing the generator amongst the usual 'kettle' noises.

As the lighting was only used when dark, the cab lights would be switched on for the steam gauge/ gauge glass. Running light engine, only two lights would be shown.
Coupled up, the rear light would be out and two lights at the front end.
There would be no discernable change in the note of the generator once it was running fully.
Most enginemen at Botanic never bothered with the cab lights at all. Still used the the colza oil lamp for the gauge glass and as we fired with the flap up there was plenty of light to read the steam pressure.
