I visited their depot when I was at high school! Would have been not long after they started up. Was doing a local studies project in what we'd now call Year 8 and I opted to do it on public transport. Wrote to several bus companies and Tame Valley and Bee Line (by then running double deckers out of a big covered depot somewhere near the city centre - sure someone will know where it was) both invited me to visit. I must have sat in that caravan. Goodness knows what we spoke about!
I hope my friend made you welcome at Tame Valley - he could be rather a spiky character!
Your mention of Bee Line is timely: I actually started my driving career with them at their Portwood depot in Stockport, now the site of the Tesco Extra. A heavily-capitalised start up of United Transport, with a brand new fleet, well-trained staff and newly-equipped premises, surely they couldn't be described as cowboys?
Well, not in the sense of many of the other operators mentioned here, no. But their original business philosophy, although superficially impressive with long operating hours on 'innovative' routes, soon retrenched to little more than competing on existing well-served trunk routes. Granted, some of their new links are still represented in the route network (say 7, 11 or the routes from Stockport to Stretford/Urmston) but many of the newly-served roads generated very little traffic, and often significant opposition from residents.
I might also rail at the poor working conditions, particularly in the early days. Split turns abounded, with unpaid three hour breaks a feature of several Sunday duties on my regular route. Running times were often very optimistic, although in fairness that did gradually seem to improve. Discipline was fairly harsh, with summary dismissal the outcome for any driver found smoking on the vehicle, even if stood on the step during a layover (if you actually got a layover!).
I left after about 15 months; the training bond was a flat £100 for 12 months, roughly a week's wage.
I assume the depot mentioned by
@mangad would I assume be Hulme Hall Road, the former North Western Road Car premises just off the A56 in the St Georges area of Old Trafford, also used by Ribble, if anybody could confirm?
