It works well for me. The main issue is the XC’s not calling there. If they did I would use it a lot more and I suspect many more would too due to the ample free parking and access to the M1.
It could be transformational if long distance stuff stopped at Meadowhall.
It’s already a handy hub between various coach services which divert off the M1 to serve it as a kind of “Sheffield Coachway” on routes that previously ran direct up the M1 omitting any stops in South Yorkshire
But, given that the shopping centre opened in September 1990, the station was designed in the darker times of 1980s British Rail, hence a maximum of four coaches per platform, just four platforms and no capacity for longer distance services to overtake stoppers
I’d like to think that
if it opened today we’d have four tracks on the Rotherham lines and platforms capable of handling much longer trains, plus a tram station on the south western side rather than having to take the tediously slow route alongside Tinsley Viaduct to reach the station…
…that would allow things like a half hourly London - Sheffield service to run through to Meadowhall/ Barnsley/ Kirkgate/ Leeds in place of the existing semi-fasts…
…but, given the constraints, “we are where we are” etc, it’ll be yet another expensive thing to “fix” if you want to do it properly
