Just for a change here's a train going the other way.  It is headed
by two of those most familiar of all S&C engines, the Black 5.

indentThere is a 3 foot radius slice missing from the baseboard in this corner so the door can swing open.  While not perhaps ideal, it does at least give an excellent viewing position for visitors who are thus actually "inside" the model.

indentAlso worth noting is the carefully chosen colour for the baseboard sides.  Black would be too strong and would distract the eye as did a bright green.  This "gentle" green is so subtle that I suspect you hadn't even noticed it until now!
