Ok, I need to do the following. I hold; Priv 16-25 Railcard Gold Card (Zone 1 - 2 Travelcard) Today (the time is now 13:49) Loughborough - St Pancras St Pancras - Euston Euston - Sydenham Sydenham - Waddon Marsh Waddon Marsh - Laindon Saturday Laindon - Euston Monday St Pancras - Loughborough, leaving St Pancras at 08:25. (Ticket already held for this leg but still worth mentioning.) Who can come up with the cheapest set of tickets . So far I'm expecting to pay £27.65.
