I'm looking at taking a train that departs from Birmingham New Street Station at 3.17 pm. I'd like to visit the Back to Backs sight and the earliest time I can book a tour is at 1 pm. If I left at 2.30 pm from Back to Backs and head to my hotel (will stay somewhere close to the station) to collect my luggage from left luggage and then to the station is there enough time to get this train? If not, what;s the earliest train I should book? I'm travelling from Birmingham to Penzance.
Thanks in advance.
