Hi Robert;
I presume you mean the Richmond Hill Live Steamers? The members that I know are all good people – it's a good club.
I know that they used to have 5" gauge on their ground level track, but I *believe* that it is now disused, after their expansion a few years ago.
The elevated is 3-1/2, and 4-3/4" gauge – I don't think there's a 5" gauge rail there.
I mention this only because Britain uses 5" gauge, whilst most of North America uses 4-3/4" – so beware of any kits from the UK, if this is your chosen route.
There is a 5" rail on the Kingston track, and Ottawa is 5" gauge, NOT 4-3/4" – what a mess!
Put the word out to local club members. You never know what's for sale; locomotives do come up once in a while.
