By itself probably not, but these things are all part of the overall experience. Warm, clean waiting rooms and toilets, hot drinks, luggage facilities, it all becomes part of the overall picture that people remember when booking next time.
By the way, there is a decent sized set of automated left luggage lockers at Fort William station, which was great for me to leave my bags at between checking out of the hotel and catching the sleeper home.
Perhaps the IRA and current terrorists haven't heard of Fort William!
If Amazon can introduce lockers at stations for the collection of items ordered online, surely it's no less dangerous to offer left luggage locker facilities? I mean anyone could infiltrate a delivery company and place a device in an Amazon locker.
Guildford railway station has plastic see through bags for the bins. For security purposes no doubt. However outside the back of Guildford railway station, no doubt on council adopted pavement, is a concrete bin. If that exploded it could easily damage part of the station and people going into it. However it seems that OK because it's not on railway property.
Therefore I think more xould be done to provide left luggage lockers at stations without the need for expensive scanning facilities and staff.
Personally when I'm travelling and I wish to break my journey, or more likely use split ticketing, I just bring all my luggage with me.
There's a second hand book shop in Penrith, called Beckside Books. Last year I stopped off there on my way from Glasgow and the previously year when heading to Glasgow. On both occasions I just brought my suitcase and other luggage in with me. I've done similar in York when visiting bookshops on route.
If I'm staying over somewhere I will leave my luggage in my hostel/hotel until I need to leave.
I wouldn't mind paying a few pounds to store my luggage but I don't want to pay huge storage costs. Perhaps stations have cheap lockers or there are near by locations that are cheap. However as lockers are so expensive in London stations and so many other stations don't have them for security reasons, I end up expecting everywhere to be expensive so don't bother to find out the truth.
