My knowledge of this area is mainly from passing a few times on the train, OS maps & also Don's brilliant MSTS route.
The Bombardier depot, which seems to be on the Derby side of the former Wichnor sidings (checked the railway spelling from an old Network Rail National Control Centre Log), is known by several names; officially it's "Central Rivers" or "Barton Depot", but it's also locally known as "Barton-under-Argos" or "Muddy Waters".
