WTF?
The motor buffet vehicles were all modernised in a works programme at Crewe from 1997-98. At the same time, units were also repainted from their original Network SouthEast livery, into South West Trains' Express livery. During 2006, South West Trains have sent some units to Bombardier at Ilford. The livery has been modified to make it Disability Discrimination Act friendly.
