>>1086117The two A4s are in the National Railroad Museum in Green Bay, Wisconsin, and in the Canadian Railway Museum in Delson (near Montreal), Quebec. You actually had a perfect opportunity to steal them back during "The Great Goodbye'' event in Britain a few years ago, where all of the surviving A4s (including these two) were briefly reunited in the UK.
>>1086094>Are there any expat British things in the US one could go see?The first thing that immediately came to mind was this place:
https://www.waleswest.com/ The Wales West RV Resort & Light Railway in Silverhill (near Mobile), Alabama uses a 2-foot gauge Exmoor steam locomotive built in 2004 (kudos to the UK for having multiple companies that still make new steam locomotives). I believe you need to reserve an RV spot at the resort to ride it, though.
