Who owns the FGW 57 fleet? Given the long history of unreliability it's long surprised me that they've not switched to hiring in something more reliable, ideally on a "service provision" basis- i.e. hire say 67s from DBS on a contract that means that it is up to the provider to ensure there is working loco.
Given that Chiltern have dropped the 67s partly in terms of their reliability I'd be surprised if they were lumped onto the FGW Franchise, but little surprises me anymore! The 57s can be good locos, but have always needed the correct maintenance and weren't really designed to do some of the jobs they've found themselves on (although certain aspects and areas of the locos weren't very cleverly designed with maintenance in mind, esp on the /3s!). I wonder too if the locos they were converted from didn't help either, as most of the 57/3 Fleet for VT were converted from Cross Country Class 47/8s - with the odd 47/7 and 47/3 at the end of it, whilst the FGW 57/6 fleet were converted from fairly tired former Freightliner 47/0 & 47/3s.
Although, that said, 57605 Has been the most reliable 57 in the FGW Fleet having made the most faultless running trips between Padd and Penzance this year, 603 however.
Speaking of the Night Riviera for a moment, all the Mk3s now have WIFI installed and as of last Friday night too is now active.
