The signal sections from Hitchin to Peterborough are quite large also and yes plenty of level crossings!
387, you know the Moorgate line has it's own rules down there we need a mini course on that too. Remember when it was FCC, they had harmonised T&Cs hence the same pay.
Ever since I've been on the TL route, it's always been said that the GN side is easier to learn and work than the TL side.
On the route side the GN is pretty straight forward end to end running. Pretty much a 4 track railway in its length, with one North south loop and a long branch up into the fens (and a stubbed branch to moorgate). Depots at Hornsey. Drivers workings tend to be short trips, change ends and go again. Somewhere in the region of 2 hours max driving end to end.
On the TL route you've got Bedford to London 4 tracked, through the core and down to brighton ( diversion routes via crystal palace, Norbury, Clapham Junction. Redhill and lewes). The Sutton loop both ways, with diversions via crystal palace, Norbury and West croydon.
Sevenoaks via Catford and Swanley ( diversions via Kent house, birkbeck and orpington).
Also diversionary routes into St Pancras high level, London Bridge low level and London Victoria. And the south London lines via north Dulwich. Depots at cauldwell, selhurst and lovers walk. Drivers workings cn be long we have a job where you go Bedford to Bedford via Sutton it's non stop in the chair driving for 4hr30. A regular loop is 3hr20 or so.
Also worth noting there was a major pay gap between TL and gn when FCC was formed, it was in the region of TL being paid 7K more.
