Heaton Chapel station [HTC] is the busiest station in the whole of Greater Manchester with 654,224 paying passengers in 2012/3, still without disabled access. When passengers using travel and bus passes are included, this usage will probably be not far off 1,000,000 passengers per annum.
11 other much less busy local stations all in north Manchester are already being considered for an accessibility updgrade. Probably three will be upgraded by 2019.
The 'Friends' have strenuously campaigned to have HTC included on this list, but sadly to no avail currently.
In reality, 2020 will be the very earliest before HTC can be even proposed for consideration for an upgrade.
HTC needs one new lift down to platform 2 and a new legal ramp down to platform 1.
This data is published on the Office of Rail Regulator Station usage 2012/3 website.
