Newby to all of this

Look at the label on wall warts. They show the input and ouput voltage and amps. Tag, yard sales, even surplus stores. If the prongs for the outlet are like USA, they might be universal, 110 to 240 AC input. I have some of those. They come in different voltage snd amps. Over the years I have trown away about a dozen I had no use for.

Online, Alltronics and Jameco Electronics I have ordered electrical stuff from stuff from.

Our European members may have some good advice for you on the Hornby.

That would be too many electrical variables for me. I’d sell them on Ebay in a heartbeat.

Any DC power pack will do the job, no need to get any special electrical equipment. Hornby trains run, just like your US brands, on 12 - 14V DC.

You have no idea how good that is to hear !! Cannot find anything with output dc low enough. BTW, is amperege a problem? his one is 0.5 amp and again, nothing that low.

Thank you “Sir”

I assume this is engine amperage? I can’t imagine a MR power supply with amp output that low.

The engine takes only the amps it needs from the power supply. The power supply does not force extra unwanted amps into the engine.

I told you those Europeans are clever. Not only they do English better than some of us, they can cook measuring in grams and milliliters and they know whether to put a coat on if the temp is 19 Celsius.

For DC: MRC power packs on Ebay are cheap and bullet proof.

No, not engine amperage. the AC adapter itself has rating of 19V --0.5A output. All I have found (mainly on Amazon) that would have 19V output has 3-4 amps output. Don’t want to mess up the controller or the engine–

OK I reread your previous post.

You have a Hornby controller without a transformer, or at least one you can plug into the US electrical grid.

I’m out of my league. There is a Hornby US site https://www.hornby.com/us-en/stockists/north-america/

Check this page: https://www.hornby.com/us-en/shop/track/track-accessories/us-transformer-for-r8250-train-controller.html

I am inclined to say “Scrap the Hornby controller” and buy a MRC powerpack.
