Princess Charlotte is a GWR Star locomotive.
Princess Charlotte 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 Charlotte will likely be painted in the Brunswick Green livery of both the GWR and British Railways.
- Princess Charlotte was originally written to be No. 4053 Princess Alexandra, but this was changed for unknown reasons.
