I looked at your 30-67699. It is 68 3/4" in length. can't get one siding that long, so I split it into two. Need an uncoupler track to split the consist. The LC engine has an electro coupler for the final cut.
Clockwise running, stop before siding switch. Cut train one from engine. Through switch back into siding and collect both halves of train 2. Pull it out, crossover to outside, back up past switch and cut it. Then past switch, back into inner, hook to tr1, pull it past siding switch, back in, cut at half, push into one siding, out of siding, back into siding 2, cut with engine coupler, leave siding, go around and collect train 2 with engine coupler, line all switches and run the main.
I used 072 for the angle. The grey shows the roadbed for clearance check.
