RE: Arriva North West - St Helens Depot
I get it MM, thanks for that. But it makes me wonder, there are 48 pulsar types at St Helens how many are needed on an average day? Surely there can't be many lying around idle in the depot because one could be fooled into thinking there was double that number.
How many are needed for a full service on the 10/10A, 320 & the 352? Routes one most commonly they are seen them on.
I know those services are not all pulsar operated 100% of the time but the pulsar fleet must have very high utilization time's.
