(Yesterday, 5:21 pm)Adrian wrote The problem with chucking everything to the far side, is the accessibility of those platforms. The lifts and subway only connect the entrance to Platform 3 & 4. For Platforms 5 - 8, you'd have to use the ramp, which is really steep for a wheelchair or powerchair user. They really need to find a solution to a Forth St/Orchard St entrance, which could resolve some of those issues, or alternatively look at lifts up to the bridge.

There are tunnels as shown in this video which have been closed since 2003 when Mail Trains stopped running that run from Platform 7/8 all through to where the Station Management Suite is on the opposite side of the Station.
The video was done a year ago and as you can see the Tunnels are in pretty decent condition giving London Underground vibes but if significant work was carried out all the way through you could have step-free access to all Platforms via Tunnel/Lifts at Newcastle Central Station.
I presume the tunnel ran through from Forth Street where Royal Mail is however there is no clear indication where the Tunnel entrance was/is as I presume it was covered up by the existing brickwork at the side of the Station.
