You're welcome! They also used to work a semi-fast pattern, but now they stop at all stations (bar Pevensey Bay) on their way to/from Eastbourne. Exactly. It doesn't feel like there is a proper endpoint to the route either. It's like if Great Western Express terminated at Slough instead of Reading or Trans-Pennine Express only went as far as Huddersfield. Eastbourne also doesn't feel like an 'end of a journey' station either. Coming out of the tunnel to Hastings to the the sight of semaphore signals and gazing up all the houses on the hills could be a really big 'wow moment' for the route. Terminating at Ore less so - it's one of the naffest stations on the network (unless you're a fan of palisade fencing) - but the Queen's Road bridge is very pretty. Since 313s only work the Lewes and Seaford services on the East Coastway*, I'm guessing Dovetail deemed it more cost effective to slap a new skin on a Class 66 and model a wagon rather than an entirely new train. *The 313s also used to operate a once a day return trip to Ore in the mornings, but that stopped with the East Coastway timetable reforms.
