The 343 is fun, going through West Vale twice, 12 minutes apart. For a while it used to extend to Barkisland, taking even longer (about another half hour).Halifax to Huddersfield has 5 variations
503 (direct in 30mins)
536 (eves and Suns via Stainland but not Elland in about 40mins)
537 (via Elland, Stainland and Outlane in about 50mons)
343 (via West Vale, Greetland, West Vale, Elland, Blackley, Weatherhill, Lindley and HRI in about an hour)
549 (via Hipperholme, Brighouse, Rastrick, Cowcliffe and Birkby in about 1hr 15)
Woe betide anyone who gets on the wrong one!
When I was in my teens I had a Metrocard for West Yorkshire - I was in Leeds and walking to the bus station to get a 508 to Halifax (At the time taking about an hour). A 226 showing "Halifax" stopped at a stop I was walking past and I jumped on, thinking a different route might be interesting (I knew the 223 and 224 took a similar amount of time as the 508 despite a completely different route). It was a longer version of today's 255 and took 2 hours. I didn't make that mistake again.
