I have an 0-8-0 from a starter set, which I bought for $75 on eBay, and my niece brought it over to UK in her hand baggage as part of a family visit.
I’m quite pleased with it, on the whole. It runs nicely, negotiates O27 curves easily; the air whistle is a bit feeble but you can’t have everything. It looks good with a 233 tender, too, or the tender from the Polar Express loco...
as several people have remarked, the motion is a bit basic and cheap looking. Is there any way to upgrade this, at a reasonable cost? I suspect the answer is “it’s simple, but too expensive to be worthwhile” but I thought I’d ask?
