Exactly so: the other tricks are making sure you're at the front of the train (good excuse for going first class London-bound), and that's it's a slam door so you can open the window rather than trying to film through glass and risking the autofocus screwing up.

I used a casio exilim FH20: that'll record 210fps at 480*360, creating a 30fps file which is 1/7th real time. The newer models do 240fps at similar resolution, and you could probably get away with converting that to 24fps for a 1/10th realtime. In the 'pricey, but still consumer' market there's the exilim F1 which captures 300fps at 512*384 (casio, if you're reading this, feel free to send me one!). All these models claim things like 1000fps recording, but it tends to be the size of a postage stamp.
For HD you're looking at ultra-expensive cameras for sports broadcasters, whilst truly insane frame rates tend to be found in industrial quality control / scientific cameras that aren't exactly designed for making youtube clips.
Basically: frame rate, resolution, cheap- pick any two.
