The X84 is nearly non-stop between Manchester and Oldham (considerably fewer stops than the tram!) and takes a whole hour; more at peak times. There isn't a motorway or faster route - could a non stop bus really beat that at all!?
The tram does it in 30 minutes bang on!
Do want to try doing a bit of research first!
1. The X84 *only* runs in the peak.
2. It doesn't serve Oldham town centre. The nearest stop being Clarksfield (the opposite side of Oldham to Manchester) with tghe slowest journey to/from there scheduled around 50 mins.
3. Its primary market is from Saddleworth, which is not only a considerable distance away from Metrolink, but has only one havy rail line (Greenfield) close to the route.
That said, there is no longer scope for Express buses to/from Manchester except through the corridor to the west of the county. Just as Deregulation forced an increase in car ownership/use in general, the "Field of Nightmares" M60 has stopped any possibility of it being constrained, especially to the east of the county. Between Sharston (to the south of the county) and Failsworth (ENE) the M60 is gridlocked nearly every peak hour, not only due to the sheer amount of traffic, but due to awful driving standards - and not just amongst private motorists! Virtually every weekday, there is either an accident or breakdown, leading to multiple lane closures and 10+ mile tailbacks. This in turn, spills over into neighbouring A roads and towns.
