First stab at a reply ... based on inputs so far. Comments welcome.
Should
GWR▸ run trains on Boxing Day? If so, what service, who would use them, and what should be done about all the engineering works going on at the time?
The question was asked of the "Coffee Shop Forum" members - a passenger forum covering the GWR territory, and over 40 of our members answered at
http://gwr.passenger.chat/274191. 76% of respondents said that trains SHOULD run , 22% no service and 2% "don't know".
2. Travel to and from sporting fixtures, sales and family gatherings. Mostly day return journeys over medium to longer distance, but some single journeys as people move on from one Christmas visit to another or start or end family visits.
2a. There has been a great deal of discussion of this over the years on the forum, and a number of our members would use the services themselves. I would be reasonably comfortable to suggest that marketed appropriatly, and tuned for the markets described, would be well used. These are, however, markets which are sensitive to fare levels and the day could present a real promotion opportunity to those who are not normally rail users rather than a "squeeze as much income as possible" day.
3. 80% of respondents who said trains should run opted for a Sunday service (other options of weekday service, strikeday service and something else shared the remaining votes). However there are a number of write-in qualifications which are worthy of a read.
4. Little comment was made on engineering works. Past experience of the markets concerned suggests that people would prefer to stay on a train with a longer diversion route in preference to a bus service. Marketed well ahead, major station closures (your Paddington example) could be acceptable provided that passenger alternatives were provided. You at GWR are experts at this - the Elizabeth line would seem a logical alternative there. Bristol Temple Meads - perhaps Lawrence Hill calls? No comment on longer closures at other times of possibly busier travel; planned carefully, perhaps Boxing Day service would be busier anyway.
