Considering purchasing one...one issue - My tunnel. My layout is 4x8 with 0-42 curves with one end of the layout in a tunnel (see photo). The tunnel walls are about an inch thick. Do the math and you'll see there isn't much room to play at the ends of each curve where they transition into the straight - away.
Anywho, if possible, can someone who maybe running on 0-42 curves give me measurements of the cab and boiler swing? I'd highly appreciate it. Don't want to drop $700+ on one and find out it doesn't fit!
