Top speed of various London Underground stock

[gimmea50anyday]

maybe, maybe not but a 442 can do 110, the speed limitations is the shoegear interaction with the 3rd rail

72's could top 65 between High Barnet and Totteridge, deff bumpy though.

on which, it is the design of the ramps at the ends of the power rails that are key. Steep ramps mean shorter gaps between traction power sections (so less chance of slow/stopping trains being gapped), shallow ramps mean you can run trains faster but have a higher risk of gapping

I wish I could go back in time just so I could ride trains where they went much faster.

I'm sure I once heard a story of a driver in a Q stock made entirely of Ms, apparently it flew...

Ms being Metadyne control?

I would have thought that it'd stand for Motors, certainly would make sense in the traditional description of LU formations, DM, T, NDM, UNDM, etc.

Ahh yes, but any motored car in LU would normally be referred to as a "Motor Car" rather than an "M" car. Since there are a fair few other things referred to as "M", namely the door...

Q Stock were not fitted with Metadyne equipment

Very valid point...

A 95 stock could do it too, although fewer people would do it due to the presence of an incident recorder on the train. Combining this with heavy braking on the approach to Totteridge would often produce a rather nice burning smell from the brake resistors, although not as nice as the smell of brake dust in times past from a 59 stock!

Nowadays it's 50 mph on this section, although some time in the future it seems likely to be increased to 62 mph (100 kph) once various issues are ironed out and in connexion with a planned timetable change. The track is a little better nowadays than in 59/72 stock days of course..

That nice smell of brake dust was probably a chunk of asbestos, depending on the year...

Still smells nice though!

I was fortunate enough to assume ownership of some redundant stuff out of the tunnels recently, covered in decades worth of tunnel dust. When cleaned up at home the smell of brake dust in the air was something else!

The Victoria line feels quite fast on the long (ish) sections (Kings Cross to Highbury/Finsbury to Seven Sisters)

Actually, the Victoria line has gravitational pull after it leaves a station

I'd love to ride a 72 stock being hauled by a Deltic flat out up the ECML.
