It could but I doubt Network Rail would like to or would
They do indeed! In this country we have multiple classifications - MU, DMU, EMU /E , HST, EPS etc etc - which apply to various combinations of EMU/DMU Classes.
The EPS limits have are also unit specific, where Class 390's have one limit, while 221's can be 5, 10, 15mph lower. Crazy as it is, that is the situation.
So why not another variant?
In East Anglia for example, the 80/90 DMU limit from Maryland to Shenfield has the followng additional instruction in the sectional appendix:
trains formed of the following classes may travel at the higher emu/dmu speed: Class 321/322/345/360/379 720 and 745 EMU's, 755 bi-mode and Class 90 electric loco hauling/propelling mark 111 stock.
interestingly Class 317's not permitted!
In Italy, there are no TASS beacons as far as I can tell - probably due to the fact that rolling stock clearances are much greater. I do recall being on a CLass 485 unit where the buffet car was clearly not tilting due to some sort of failure - but we were still maintaining the higher 'P' pendolino limits. It was a lively ride to say the least in that carriage.
Could TASS beacons be fitted to Class 397's and Avanti Class 80X to monitor for overspeed - even if there is no tilt system to manage?
