Hello,
All 153s, 156s, 315s, 317s, 321s and 379s will be in either GA white with blue doors, GA white with red doors or NXEA silver & white with blue doors by the end of the franchise. There are no plans to repaint the 90s or mark 3 coaches or the 360s (indeed, 360115 which was vinyled into NXEA silver/white was recently returned to its dark blue FGE livery) and it is unknown wether the 170s will be repainted or not.
All units/coaches will receive a deep clean both externally and internally and
321421-321437 will receive
new interiors as these are the ones with the former Silverlink blue interiors.
Adam
