How much does a Canadian weigh?
Well, if it's the train, it appears to be
19 cars, at 50 tonnes per car (I assume the 'customary' weight.)
2 engines, at 118 tonnes per engine (EMD F40PH)
Total 1186 tonnes
OK, that's one heavy train.

Do mach numbers apply in vacuo?
And much less rolling resistance
That's a very good point: deformation of all that tyre rubber isn't something I considered.
I found it interesting that the Montréal Métro uses rubber wheels, as per Paris, while the Vancouver SkyTrain uses steel wheels. For something passing over people's heads, the SkyTrain is remarkably quiet, lacking the screeching I'm so used to with the London Underground.
