We enjoyed this! The trains ran to time, every 30 minutes. We did a return journey & got off to spend a short while at far end where there is a pub (live music today, a Saturday in July) & a small cafe & gift shop, There's a fair amount of parking at the far end, & a large EV charging hub so you could start from this end & use the train to get to the promenade. There's a path alongside the railway, looks tarmacked the whole way & good for wheelchairs / pushchairs too - guess you might do a single trip & walk the other way (about 2km). The train has a wheelchair accessible carriage for 1 wheelchair or mobility scooter per trip. We got on without having to wait. Our group, 1 in wheelchair, 2 other adults & a dog fitted in the carriage nicely ..,a staff member was there to put ramp up & down, & safely lock it, without us waiting.
