Nicely done. One small quibble, a "siding" is a railroad term with specific operational meaning. It is a double-ended track off the mainline available to the dispatcher and/or train crews to utilize for trains to meet or pass. The single-ended track where you dropped the box cars would be called a spur, house track or industry track but never "siding".
Hey bill just joined the railroad any way u can help understand trailing points switch so I can keep the cars on the track. Please any videos or pointers that u can send me would be appreciated. I will send u my email. Thank you
