Strange, as there's usually 2-4 units out per day now in my experience.
Certainly, staff said an increase in new units was coming this Wednesday - with the Stadlers running out from start of service now, instead of more limited times.
Maybe I have just been unfortunate with timings. They've all been week days at very mixed times morning, afternoon and early evening. However, the news of them running from the start of service is good!
I wonder if the increased number of units in the depot is causing issues with exterior cleaning and such? Some of the older stock are now quite filthy on the outside, particularly the top of them, in a way that was never really the case in the past.
