You can take the 08:46, arriving in Manchester at 12:13 - an average speed of about 60mph.

The £300 is an option that few choose, because that journey gives them major benefits. The money raised from that is plowed back into the railway and used to subsidise services to Harrogate, Holyhead and Hungerford
