A pilot training course was run last week to try and nail down what bugs were happening; apparently ARL and ASLEF both agreed that no more training could happen until the software is fixed. It's simply that buggy you can't actually learn on it because it keeps falling over.
That said, they did suggest some of the managers are receiving some training this week.
In light of the above the month's free travel that had been promised as compensation for when the service is fully restored might be a while off yet!
Looks like a 710 is back out today - perhaps for the managers' training as you said. Nothing ran Monday or Tuesday. Interesting that the trains are still deemed too buggy given the runs last week ran pretty much to time but that is just one of probably hundreds of aspects that Bombardier and others are looking at. There are also continued overnight runs on the WCML. This at least is movement on from having trains sat in depot going nowhere.
For those bemoaning the use of new trains there seems to be a bit of memory failure going on. When the 172s turned up they kept breaking down and there was all the furore over the exhaust systems potentially not being compliant. I believe the 378s also didn't have a fault free introduction either. Every so often we have to go through a generational change in train design because requirements change, passenger expectations change and technical and safety standards change to reflect lessons learnt over previous decades. The Aventra is a step change in train design. When it works it has the potential to be vastly more reliable and cheaper to run than previous train designs. That's not to excuse the enormous delays in getting the things tested and certified but perhaps it partly explains things. There are a load of new technical challenges that have to be resolved. AIUI not all of the issues that have been encountered are down to Bombardier anyway. Some of it is the infrastructure performing in ways that were not expected - i.e. outside the range set in standards. Bombardier have built a compliant train but it stops working (correctly) when it encounters non standard power ratings in the electrification. That's not Bombardier's problem - that's the result of how NR have designed and built the electrification infrastructure and power feeds and the level of use at certain times of day on lines away from the GOBLIN.
I'm as fed up as the next person with what is (not) happening with the 710s but I do think we will get there eventually. It's just a very long slog and not all of the issues are to do with the GOBLIN electrification either. Demands to get Crossrail working and delivered will also be putting a squeeze on technical resources.
