Hull Trains has announced it is now running extended 10 carriage trains on a number of its services from Wednesday to Sunday due to growing passenger numbers, bringing an extra 4,000 available seats per week for customers
They were certainly running 10 cars when went on holiday in October. It was a Saturday and they were full. Advance fares are reasonable and journey is a lot more comfortable than changing at Doncaster and joining a packed LNER service. For a secondary destination the roughly 1 train per 2h is probably about right, and you are better dealing with increased demand by running longer trains than trying to run more frequently, even if that were possible on the ECML.
Would they lengthen to 8 or 9 car or try and and order some more 5 car units?. I dont think they could run 10 cars (or even 8 or 9) to Beverley, only 4 of the 5 cars fit on the platform, and Howden is a challenge, the back unit is completely off the platform.
Have they ever expressed a desire to run extra services to / from Beverley, or extending those services to Bridlington?
It would be useful, but I am not sure if there is enough business to justify the extension. Beverley - Bridlington is 28 mins calling at Driffield, so if they extended the 06:05 from Beverley back to Brid you would be looking at a 05:35 ish departure, are signal boxes open? Brid station doesn't open until 06:00 I think, so yes we would use it, and it would give a useful early departure, but our few times a year custom isn't going to make the business case... We have travelled from Beverley a few times and custom seems to be picking up, so I really dont know, Hull trains seem able to develop markets, but I am not sure there is a market to develop.
