But we still need to know what breed the cat is!

And, is it walking towards the front of the train and causing more resistance as the Earth rotates, or to the back actually pushing it along?

Edit: Actually if the train is travelling exactly North or South the rotation of the Earth would not be a factor.

I suppose it depends on whether you are your way to work, or on your way to a bar ...

If NASA doesn't concern itself with converting metric to US for its Mars probes and other things (0.3 meters per second to 0.3 feet per second equates to over 3 times faster, or 1000 gallons of fuel but only put in 1000 liters so it runs out) then conversions must not be that important - the train is still moving, unless a NASA probe falls on it.
 
Schrödinger's New Cat:

If a cat gets on an AMTRACK (USA) train when is it considered dead? As soon as it gets on, when the train crashes or when the train was supposed to arrive somewhere?
