The sidings on the Canadian Sub can handle over a 100 cars. In fact sometime they run 10,000ft. long trains over the northend. Sidings in Ft. Edward, Whitehall, and Bluff Point are 10,000ft or more. Ticonderoga is only about 4800ft, but if a train holds in this siding it can't be more than 4400ft. due to the two private crossings at the southend of the siding. This is the same for Wadum's, its 5800ft. long, but good for 5400ft. due to a crossing at the southend of the siding. Howard's siding in westport is a little under 8,000ft. A new siding in Port Douglas (rockland) will be in service soon. That siding will be around 9600ft. The last siding is Rouses Point. That siding is 5800ft. Keep in mind that rail cars come in different sizes. A intermodel train may be 30 cars, but the length could be 10,000ft long.
