To save bits of stuff being posted on the GWR Livery and Night Riviera threads and elsewhere, decided its about time that this was put in one place. So for those who dont yet know, some 11 sets of four car HSTs are being used for mainllne stopping services between Penzance/Plymouth/Bristol starting dec 2018 timetable in lieu of cascaded 158s which are delayed/cancelled due to IEP being behind schedule. They are to be fitted with CET and sliding doors. 24 power cars are being modified and will be retained after the introduction of 800/1/2 fleet. Livery will be the new green. They are expected to be in use for some time well into the next franchise. Coaches at Doncaster for modification currently are: TS: 42093 42168 42177 TGS: 44055 Power cars are to come from the Firstgroup owned and Angel Trains leased batches. So far, the following have had cab desk to air cubicle wiring added in readiness and a repaint: 43093 43188 43194 43198 First set due at Plymouth in july for extensive testing before second set is done. A diagram has already been identified, m-f 0600 ex Penzance, for testing.
