Do XC Voyagers have tilt? I thought Virgin retained the Super Voyagers which do tilt.
How fast do Virgin Voyagers go down the Trent Valley (eg Holyhead - Euston trains)?
Why would switching off tilt on a Super Voyager make it faster? Surely the whole point of tilt is to run a higher speeds round bends?
I must have got you confused.
To be clear, VT's 221s are TASS/tilt enabled and can do 125
EPS on the WCML.
XC's 221's have TASS/tilt isolated so are limited to non-EPS speeds which are 110 on the WCML (and 75 at places like Atherstone or Queensville, which have 85 EPS).
220s were always without tilt so are stuck with non-EPS speeds.
For reasons I don't understand the non-tilt Voyagers can do 125
HST speeds between Bushbury and Stafford, but are still limited to non-EPS speeds north of Stafford (via Crewe or Stoke).
I have been on a VT 221 with a tilt failure between Euston and Crewe, and it stuck to the non-EPS limit of 110 throughout (but still managed to keep to time!).
I know this because it displayed the real-time speed on the internal PIS display (something I have never seen before or since) and the guard confirmed the reason.
