[Closed] Recommend me a... steam-train driving thing

So, my brother's a train nut, and we'd like to send him off to drive a steam train. He's done a diesel train before and tbh that looked absolutely rubbish but he loved it anyway, so a proper train should blow his mind...

So, looking for suggestions of good ones, really, there's lots out there. Ideally central belt of scotland, or around leicester. The more involvement, and the cooler the loco, the better- and if his girlfriend can tag along without us having to pay £200 odd quid for her to stand there and take photos, that'd be grand too! I don't think she'd want to be actually involved but they're pretty inseperable.

Any help much appreciated.
