Jijun,   Tried your .exe with "Large Address Aware Binaries" turned off and still got the same crash.  Have attached log and path file.  Please keep in mind that I am using the Surfliner route from Facing Point Media, not the freeware Surfliner route from train-sim.com

 Subject: [Bug 1429666] Re: System.IO.InvalidDataException at ORTS.Simulator.InitializePlayerTrain (X2913, Pacific Surfliner)
   
Please see if the newest experimental code fixed this problem. If not,
please attach the path file for the surfliner route so I can test.
