Given how long it took to get the 730/2s into service and they have now been in service for 12 months, it's pretty poor that something as basic as emptying the toilet tanks is still an area of concern.
Crewe is not classed as a maintenance depot for class 730. It's only classed as a stabling point. Which is frustrating as this allows 730s to enter service at Crewe without working toilets, as happens from time to time, and they won't empty them during the daytime either. Needs to improve, far too many run around with 1 or no working toilets (out of 6). And yes, I do know this first hand, I work them daily.Crewe is a maintenance depot. They do plenty of work there for a variety of trains.
