There was no pot bellied stove in it - certainly between 1976 and 1981 inclusive...... ermmm... I can absolutely assure you of that! There were however some very old rather soggy Railwayman's Operating Instructions - the newsprint type booklets that contained details of line closures, warnings, engineering works, temporary speed restrictions etc. I spent my formative years 'spotting' here. I lived 10 minutes walk away, and would be found there with my spotting mates after school, school lunchtimes, weekends and all day long school holidays. I've sat hours and hours on that footbridge that led the the underpass (which had not been lined with corrugated metal at that time) and to the row of houses at Heaton Lodge. Spent hours wandering round the abandoned Mirfield shed (That would make an ideal extension to give you something to do when the main part is finished!). The big embankment on the South side of the main lines made I assume from excavated spoil from the construction of the Ex-Midland goods line, was called 'Doggy Bank' - for reasons lost in the mists of time. Class 124 Trans Pennine units were the order of the day along with the Liverpool-Newcastle (and vice- versa) expresses normally hauled by a 40, 45, occasionally a 46 or in latter times 47's. From around 1981 on winter mornings the Huddersfield-Leeds 07:40, normally a 2-car DMU, would on many occasions be subsituted for three MK1 coaches hauled by a class 31. Oil trains off the Calder valley, normally with a 40 in charge. Rarities would be in 1979 a class 24 on a weekday evening going who knows where with what looked like old parcels stock. Sunday afternoons would see the resident Huddersfield station pilot 08 head back to Healey Mills (slowly!) to refuel for the following week. 20's were a rare sight, but we did get our fair share of 25's, sometimes double headed. 37's were common as muck on all classes of freight. We witnessed the first Romanian-built 56's with MGR's, saw the passing of the 24's. Saw the APT being loco-halued one toward Leeds having come from Manchester direction, also an HST in 1978 which was way off its normal stomping ground - Never saw the 58's or 60's in operation here - as I'd moved on the things with two wheels, and an engine and also that other species with wobbly-bits by then. What great times and I can say without a doubt your model really captures the exact feeling of being there all those years ago. Sadly - I didn't take photos in those days, so I've nothing to share, but I do have my spotters books and some notes..... as well as the booklets (now dried out after 40 years!) from the lineside hut . If you have any questions from a witness (albeit slightly earlier than your period) - feel free to ask and I'll try remember details.
