Wycombe branch pick-up coal task. Maidenhead to Oxford Pickup Goods service

This working was split in two. A crew worked a loco from Oxford as far as Princes Risborough and another started at Maidenhead.
They met at Princes Risborough, exchanged trains and worked back to their respective depots. There was rarely an traffic to hand over.

This Maidenhead working is only dealing with coal wagons, collecting empties from yards along the branch to High Wycombe and leaving them for collection at Princes Risborough. Exchange locos there with the Up crew from Oxford. Collect full coal wagons from a siding north of the station and distribute them along the Wycombe branch on the way back to Maidenhead.

You will be doing a lot of shunting, best save your progress frequently.

Select the 56xx and build your train with 1 Horsebox and a Brakevan then propel them into the Bay Platform and change the points for the Branch.
