I usually do Attleborough - Sleaford splitting at Spalding. But next week I need flexibility to come back via Grantham. I was investigating splitting options via PBO to facilitate this. I usually catch the 0833 Peterborough to Lincoln service. I saw this ticket, which at first would appear to allow me to use the 0833 as it's valid after 0830 via Spalding: But I thought I'd better just check the small print: So it's not valid on the 0833 after all. There is no other departure from Peterborough to Sleaford via Spalding before 0930. So what's the point of differentiating the outward validity time via Spalding if the one particular service that would allow you to use is prohibited?
