Dave, that was a key reason we changed TT suppliers after the first pass at the track plan. If you look close on two of the pictures a short white stripe is visible under the center of the tracks at the edge of the TT pit. The bridge stops wherever it detects a white stripe, any increment, any spacing. This way the TT only need enter the CAD system as a 22" diameter hole. Coincidentally my track plan is the same outer dimensions as the main part of this layout. My layout is 17'x21' but the track outer dimensions are 15'x20'. Minimum radius is 30", minimum turnouts are #5 yard, #6 mainlines.
