In this case, would trains tip out on the westbound platform at Waterloo, before a shunt move to the eastbound platform? Just curious; apologies in advance if I got my line descriptions wrong!
Stratford – Waterloo, every 5 minutes. Train Operators will step back four trains at Waterloo for most of the traffic day on Saturday and Sunday. On arrival of the train in the westbound platform, the second Operator will join the train in the rear cab. The first Operator will drive the train into the reversing berth on the westbound line. The second Operator will drive the train back into the eastbound platform where the first Operator will disembark and cross over to the westbound platform.
Slightly off-topic, but does LU use 'shunting' shifts?
As in, instead of drivers stepping back, Driver A enters terminus in service, drivers B and C enter the train at the back and front respectively, C drives it into the siding, driver B out of it, and in that time driver A has walked to the opposite end of the opposite platform and drives their train back along the line. Drivers B and C walk across the platform and do the same for the next train.
This has the advantage of drivers staying with their train throughout their shift (apart from breaks), while still allowing extremely short headways, particularly if there is more than one reversing siding and an island platform. Drivers B and C have a slightly more monotonous shift, but wouldn't that be much simpler to roster operationally, compared to stepping back 4 trains?
Typically, stepping back is used. That is driver A arrives from Stratford and driver B boards the train in the rear cab. Driver A then drives to the reversing berth beyond the station. Driver B’s cab is now leading and this driver then drives across the crossover into the station. Driver A now at the rear, alights while driver B continues to Stratford. Driver A then walks to the arrival platform where they become the equivalent of driver B for a subsequent reversing train…
