i think the central is fastest tube, also it may be the fastest line at
100kph (62mph) towards epping and ruislip

No, new coding now, since Chancery Lane, in ATO to 85KPH just over 52mph.
They will still motor, in ATP coded manual, to the100KPH but this is banned
to drivers. But it is still the fastest even with this.

I would say the CENTRAL IS the fastest line because someone below in this
thread just said the MET was now down to 50mph, so CENTRAL beats it by a
measley 2mph! at 85KPH, in the open sections of course. And as for the
Jubilee well thats 50mph too but they allow these in the new tunnel
sections, which is remarkable in itself. All other tube lines tunnel
sections are restricted to 40mph 65KPH.
