Thank you for your reply, and you are correct, with some diligent searching we found a photo showing the installation. Interestingly, the sand dome has a functional valve and does, indeed, seem to have a practical purpose. We have found that with a load of passengers and a damp track, pulling a slig...

We at the Gold Coast Railroad Museum in Miami are restoring our Crown Metals "Little Toot" loco -- the 24 inch model. Somewhere in the past, the tubing that carries sand from the sand dome to the wheels was removed. We'd like to replace it, but have been unable to find any photos or diagra...
