Yes, it is the replacement for the conversion, and it's probably justified as Leicestershire only have USAR pods, not an HVPU. Out of interest, the Tyne & Wear HVPU is also their own as opposed to being a ND issue.

Shropshire had a Medium Volume Pump based at Shrewsbury prior to the ND HVPU I think this is were the idea came from for the larger units.
