I caught the "early" Virgin service to Blackpool from Wigan last week (1112), about the 3rd time I have used it.
It's always nearly empty - there was just one other passenger in the first two coaches.
It leaves Preston for Blackpool among a cluster of Northern services and is largely ignored.
Things will have to look up if the service is going to be viable.
It also has a very slow schedule, compared to the Glasgow services.
On the plus side, its a 390 that otherwise sits idle in London during the day, so in theory the marginal cost of running it ought to be relatively low.
