Princess Alexandra is a GWR Star locomotive.
Princess Alexandra is based on a GWR 4000 Star Class 4-6-0. A few members of this class were later rebuilt into Castles. One survives today, 4003 Lode Star.
Princess Alexandra will likely be painted in the Brunswick Green livery of both the GWR and British Railways.
- Princess Alexandra was originally written to be No. 4054 Princess Charlotte, but this was changed for unknown reasons.
