First of All,
CA John, don't panic:4913 (San Luis-Hanford), is considdered by the Amtrak Computer to be a train since the bus connections are given train numbers which correspond to the numbers of trains to which they connect. (Same for 6234, 4784, etc.). Indirectly, the Amtrak trains were mentioned, because I pointed out that Leff St. was one block from the train station.
Don't just flame before you read the whole message. You are just like looseifer on trainorders, reply without forming educated opinions. Amtrak Thruway Buses are part of the Amtrak Rail System.
