I have an Advance from Harwich International to Birmingham New Street. I will be changing in Manningtree, Liverpool Street, Euston. I have bookings for all trains. I only have three minutes to change trains in Manningtree. Does that seem reasonable to you? I generally allow fifteen minutes so am a bit concerned. I could get an earlier train to Manningtree. Buying an extra ticket for that journey but that would mean starting at later station on my Advance. Alternatively I could just go with the itinerary and possibly miss my connections in Manningtree and then London. Thank you Stephen.
