Aren't they intended to work the Swanline services? If so, they'll be going through Pyle which is HST 100 I believe but given that they will be stopping at Pyle if going through there that is probably accademic.The maximum speed for the 231 routes is 95 if they're allowed to run at HST speeds - otherwise 90. Again, the improved acceleration over the units they're replacing should provide a decent upgrade without needing any changes to top speed.
