They seem to have gone backwards quite a bit from what the original station design was at Huddersfield. Whether they will get somewhere close to that by the end of all of this remains to be seen.
From what I recall I think there were 8 platforms for a lot of the br era. Even if the bay platform where the bike racks are now disappeared some time ago and was only really used for parcels even back then. I seem to remember it was 4 tracked in the main through lines at that time before any cutbacks started as well.
I'm guessing one of the main issues at the moment is that people are getting quite frustrated with the constant closures (speaking from my own experiences).
Huddersfield may have had 8 platforms but by the end of the sixties only six were in passenger use:
1 Main up (Stalybridge bound) passenger platform
2 Sheffield bay
3 Kirkburton bay, after the Kirkburton passenger service was withdrawn used only for parcels
Two through roads under the by then missing lantern of the Euston roof, this became a problem when platform 1 was moved out in 1991 and would be an even bigger problem after the recent building out if the lantern were not being reinstated.
4 Used for a variety of services, the daily Huddersfield/Halifax - Kings Cross portion reversed here.
5&6 East facing bays used by local services to Leeds and Wakefield Westgate(for Kings Cross)
7 West facing bay too short to be of any practical use. It may have been longer at one time but the building of the signal box on the 4/8 island meant it couldn't be any longer, this would be before my time.
8 Main down(Leeds bound) passenger platform
I have a vague memory that for a while (possibly before it was built out) platform 1 wasn't used much and platform 4 became the main up platform. Perhaps someone else can confirm this.
Remember that by then there were no local services west of Huddersfield and only an hourly service of Leeds - Manchester & beyond trains, mainly Trans-Pennine units with a flurry of loco hauled service in the morning, round lunchtime and early evening. It was thin times for a trainspotter who wasn't much interested in units. The service nowadays, even with the disruption, is so much better.
