Many regional rail routes operate with three and five car EMU and DMUs. I'm sure that we could handle the costs of a cross-province regional train network if we could use the lighter vehicles the European networks use, instead of the ten carriage double-deck trains that seem to be GO's desired standard.

GO's current "standard" is 12 car double decked trains.....where platforms can only accommodate 10 car trains...they are being worked on and extended.
