Lester, I'm sure that would be a popular posting ! I can imagine the preparations...LPBs measuring everywhere with 3.5 cm poles, making sure nothing "touches", before committing to the move. The old PRR/PC/Conrail track centers were "not less than 13 feet" on tangent main tracks - quite close for 0-5-0 clearance in most scales - and somewhat more on curves. With reduction to two track mainlines (from 3-4 main tracks), or single tracking old double main, side clearance restrictions are much less a problem...mostly through old interlockings, cuttings and tunnels where more room is problematic. Railroads adding multiple track lines now probably adjust centers for speed, curvature & super-elevation (due to long and high cars), etc. A "High & Wide" or "Clearance Train" with a single, or multiple extra-dimension cars could be an occasional fun challenge for model ops. Looking forward to the next "oversize load" Bob C. 8-)
