Does the Reno Fun Train still run? That would be as close as an example, it's roughly the same mileage, I believe. Also, the track from LA to Yermo (where the LA&SL takes to its own rails) is very seldom single track running, it is almost all double or triple track. There are plans being worked on for triple tracking BNSF over Cajon, so far from Ono to Keenbrook has been triple tracked.
