I'd like to nominate Mirfield as one of the worst stations around here. Sure Ravensthorpe is more isolated and run down, and Deighton is in more hostile surroundings, but Mirfield is used by the best part of 500,000 passengers a year (2015/16 statistics) and has 3 daily services to and from London. The station is unstaffed of course, and the main island platform is slowly sinking into the poorly infilled former basement space. Only one face of the island is in regular use (P1) and is sparsely furnished with a few benches, with a large but doorless shelter. Bike shelter, PIS display (P1 only), and a few cycle lockers placed for some reason halfway up P2 which has absolutely nothing else on it. P3 is a 1980s addition, in the typical WYPTE style of the time: wooden platform, bus shelter, a few red metal benches.
With the TPE reorganisation coming up, Mirfield is likely to increase in usage due to a faster and more frequent service to Leeds and Manchester. It may also have increased use for interchange, depending on the finer points of the eventual service pattern.
Ideally it would be staffed at least part-time, and with a permanent ticket office rather than just two blokes with a ticket machine. Problem is, where do you put it? The car park by P3?
I don't imagine local residents would be too thrilled with that, nor would those heading towards Leeds enjoy their extra walk... On the island platform? Awkward for anyone using P3, and the platform is apparently vulnerable to subsidence... Oh, and it would be very tricky to make accessible too.
With the TPE route upgrade possibly involving significant changes to infrastructure particularly around Mirfield and a mile or 3 either side, would it be worth just ripping the station up and starting again?
