When the Kembleford Choristers eventually arrive at Worcester Cathedral, Mrs McCarthy asks Sgt Goodfellow if he "still has the robes". He appears to retrieve them from the rear of the police wagon, and the group are later seen changing into them before giving their performance.
However, in the earlier scene when the group are departing Lower Swaddling, the basket containing the choristers' robes is clearly left behind on the luggage trolley at the train station.

The choir are waiting for a train at Lower Swaddling station and are sat on a platform that clearly has no rail track next to the platform. There is another platform with track on the other side but no-one seems to notice this.
At "Lower Swaddling" station, you can clearly see that there are no tracks at the platform they're on; only the tracks on the opposite platform remain in place.
