If saving money and flexibility are important, then I suggest:
Anytime Return
GLASGOW CEN/QST -
BRADFORD YK STNS route
VIA APPLEBY £52.50 (2013 rate, reduced to £33.25 if you hold a national Railcard).
which can be used:
Outward (
valid 5 days)
Friday: Glasgow - Appleby - Leeds
Saturday: Leeds - Bradford
Return (
valid 1 month)
Monday: Leeds - Appleby - Glasgow
If you are starting from a suburban station, the fare is available at this price from 39 stations and at about £3 more from a further 41 stations.
Then buy Single tickets (2013 rate, Railcard fares in brackets):
Sunday: Bradford - Harrogate £8.20 (£5.40)
Monday: Harrogate - York £7.90 (£5.20) and York - Leeds £12.20 (£8.05, not before 0930).
This gives a total cost of £80.80 (£51.90). A cheaper total may be available by giving up flexibility and buying Advance single fares for the long-distance legs of the journey. Check
East Coast.
If speed and flexibility are more important than price, consider the Off-Peak Return
GLASGOW CEN/QST -
LEEDS route
ANY PERMITTED £98.10 (£64.75). Valid on any train by any Permitted Route.
