Monday: Returning Journey to Liverpool

[gmhs03]

Hey all,

Am totally confused by what the website says about shuttle buses / trains on he Monday :

NB: Please note that all the buses returning to the station (castle Cary and Bristol Temple Meads) on Sunday and Monday are timetables to arrive at the station for the last train. Don’t travel to the station outside these times as you will have to wait in the car park without any facilities.

Does the above meant that there will ONLY be a shuttle bus to Temple Meads to get the last train at 8pm???

I need o get to Liverpool for work on Tuesday and best way probably will be train from Bristol.

If I want to get the shuttle bus from Glasto to Temple Meads can anybody tell me how long that leg will take?

What time will I need to leave the ground to catch a 3pm train from Bristol?

Thanks for any advice!

Confused!!
