Thanks. I gather that the Heljan locos aren't just a little bit inefficient. Pity. One option would be to have a battery van or coach behind the loco, connected by wires. Not for purists and a bit of a faff to run. I shall have to ponder.

I have a home-brew Hymek weighing 3kg and with an inefficient Cardan shaft that works fine on AAAs, but I am really thinking of the rest of the train weighing 2kg. (I.e. plastic). Obviously more would be good, but I would still be tempted at 2kg. It seems to me that the ability to start on a hill is the critical thing. Would it require the full 12V? Or start to crawl by 9V at most? I had thought Lithium would be the way to go when I started, but so far AAA or AA have been more flexible in space. And they are a bit less scary to use. But does anyone know what space there is for batteries? Ta.

How much power does the Warship need, and how much space is there for batteries? E.g., is there space for 9 AAAs (1.2v each) and would they be able to start a light (e.g. 2kg) train on a moderate slope (e.g. 1:50)? I would like an RC version for a garden railway. (Sorry if anyone has answered this, but I'm getting lost around this forum.)
