I think I've just come up with an inexpensive and workable solution to improve matters for the many women who currently have to push their children in buggies for 1/3 of a mile in all weather and with all the noise and smoke billowing out of lorries blasting by within 5 or six feet - just to get from one side of the subway to the other.

The main stairs of the subway have a gradient of 31 degrees - so reduce its width by 1/3 and keep 2/3 as is. The narrower part could be 'ramped' at say 14 degrees with very shallow, elongated and slightly-sloped steps, which would be covered in a non-slip tarmac. A similar thing- albeit 3/8 and 5/8 appotionment - could be done at the Perry Vale end and the overall result would be much more buggie-friendly - and maybe even do-able in a wheelchair (?).
