^I can't speak to how steep the side slopes ought to be - but - Electrification will require space for poles on the outside of the track clearance, and signal towers - and they may want some flat ground for work equipment and for people safety outside of the tracks themselves. Also for signal bungalows, which may need a bit more clearance on electrified lines.
A comparison might be to the Weston Sub - here's the Weston just north of the Nickle Interlocking - 27m from one sound wall to the outside of signal bungalows on the other side.
PS - the Weston Tunnel is about 19M wide.
