I actually feel a little bit sorry for Serco here. They are being let down by their suppliers. With such a complex logistical marathon every night just to get the sleepers running they need to be able to count on every part of the supply chain whether it is down to traction, traincrew, catering, cleaning etc, each thing plays it's part and if one fails it all fails.
What I cannot understand though is Serco's take it on the chin attitude towards these things. It's not the same Serco that I know that would fight tooth and nail for every lost penny. Maybe there are severe words being spoken behind the scenes but there doesn't seem any urgency for these matters to be resolved. I think it is way past the point that the recent failings can be attributed to teething problems.
Serco need to realise that they are being slaughtered here by their sub contractors and senior management have to sort this before it is too late. The reputation of the overnight sleeper is fast eroding and it is becoming a gamble that you may turn up on time or a chance that you won't.
