Hi Ivy. If I were you, then I'd post my messge in the main 'general discussions' forum - as you might be waiting a long while here. This section of the forum doesn't get much traffic. :)

Have you tried asking Raildriver?

@Timothy

I've contacted Raildriver and Areosoft bout it. Still no answer yet. However, I've found a picture of someone who was selling his raildriver and he had a non-raildriver power supply attached on it. I saw the specs and if it works for him it may work for me too. So I am thinking to order a similar one with same specs.

@Growler

You are totally right but general is for the game itself. I hate clutter :P

That seems remiss of them. As does not having a ratings plate with some details other than voltage.

As a rule I hesitate to ask such obvious questions but sometimes the obvious course of action is the one that is most easily overlooked. Like have you Googled it? Well of course you have but did you look at the images the search turned up? This one could be helpful:

That's indeed the picture I've found. Haha. What a small world.

Great minds think alike. (What's the rest of that phrase...? Doesn't matter.)

You could also try asking DTG. Matt Peddlesden there, who posts all the videos, certainly uses one if no-one else does.

Try this link - http://www.lte.com.tw/productadaptor.php?id=112 it's the adaptor manufacturer's site. Scroll down and you will see a list of adaptors. The model I have for my Raildriver is: LTE18E-S2. Not sure where you would be able to purchase one from though. A search isn't very helpful but there might be an equivalent available somewhere.

Yeah. I think any 12 volt 1.5A 100v - 240c 50/60hz will do. Only need to be carefull with the wattage. I bet.
