Does this and the other former railways you've added recently actually exist in any physical way on the ground? This one appears to go straight along roads and through buildings, for example. You might want to take a look at the  OpenHistoricalMap project (where this railway doesn't appear to have been mapped yet: https://www.openhistoricalmap.org/#map=12/34.0020/-118.3890&layers=O&date=2005-07-13&daterange=1824-01-01,2024-12-31) than OpenStreetMap, which is a representation of the existing world.

Best,
