// Light rail / metro scheduling.
// The client owns the whole carriage simulation: MetroManager builds the carriages, drives them
// along the baked MetroPath of a line and plays the gate/door animation. All the server has to do is
// answer AskGetAllMetroInfos and then keep telling the client "train X of line Y has been running for
// Z seconds" through SyncRunningMetroInfos - MetroClientInfo has no position field at all
// (Id, LineId, ElapsedTime, IsFinalTrain). That is why this feature needs no client patch.
// The schedule comes straight out of the client's own Rail*Config tables (RailLineConfig /
// RailStopConfig / RailStationConfig), which the panel exposes as "where is the train, which stop is
// it at, how long / how far until the next one".
// Round 54 got the scheduling right but not the clock: see MetroDefaultTimeFactor for the round-55 fix.
