Updated MTIN chart for Aventras as of July's Modern Railways Mag data:
The 7-car 345 data is very up and down but seems to average around 7000, so by approximation, similar to the pairs of 315s they replaced. Borderline acceptable for Crossrail services but should really be better to avoid routine disruption due to train faults. Bombardier's own S stock units, more intensively worked, achieve almost 10x these numbers. Fair that any non-critical software defects on the 7-car are being left as is so that the 9-car units can be made ready for use, but that's not something that would be affecting the 710s, supposedly now having matured after getting over the issues they experienced initially, and indeed, indicate what reliability can be expected of subsequent Aventra fleets.
The 710s seem to have 'settled' around the 2000 mark, very much bottom of the pile for EMUs and that includes the troubled 331s and 755s. Quite why this is the case isn't clear. At almost a year into service, it's a score lower than the 'first of their kind' 345s were achieving in 2018, and indeed their better-performing (although still unacceptably unreliable) competitors from CAF and Stadler have been in service for a similarly short period of time if not less. I would really have expected to see at least some signs of improvement by now.
