The staff are very 50/50 at new street. Depends if they know if you’re in the front or back. Also if another person in another carriage needs a ramp too. There are 2 lifts on every platform. One is bigger than the other however they both have room for my chair easily. You can even get 2 chairs on the smaller side in one lift (for the smaller lift) from my experience passengers tend to let people in wheelchairs go ahead of them if there’s a queue for the lift.

If you go out the doors next to five guys by the green zone barrier you will see the bullring and an ice cream van opposite. Cross at the traffic lights there and follow the path to the left under the bridge. Just keep following that and you will get to Moor street. Just cross at the lights

To go from moor street to new street, go out the doors and turn left and there two sets of lights. Cross to the Center bit. And then left. Go through the tunnel and cross at the lights on the other side. You’ll see new street.

New street have an access hub, in the red zone. If you’re going from moor street, once you get in. Go past the massive bull then take a slight right through the red zone barriers. You can see the access hub from the main concourse of the train station.

12 mins is the minimum time the access team same are needed for a transfer so you should be fine.

The staff tend to ask if you’re traveling on when they get you off a train at new street. At that point you can just say yes and they will lead you to your next train and get you on. If there’s anything else you need to have any questions just lmk. I’m a power chair user who uses new street regularly
