Redditch and Worcester Shrubhill
Does Haywards Heath count? There's a tunnel a few hundred yards to the south, isn't this particular tunnel the biggest barrier to four tracking the route between Balcombe tunnel junction and Brighton?
Was Tunnel Road Tunnels the answer?
And Aberdeen?
has Kings Cross been mentioned?
That's just a bridge with a building on it. If that counts then so does Ealing Broadway.
Has Southampton Central made the list?

North Queensferry.
Very good point - I think it does! Not sure how I forgot that one from my list. Though some might argue that Balcombe Tunnel and the Ouse Valley Viaduct are the rather larger obstacles to quadruple track!
Kidbrooke is pretty close to a tunnel.

Funny you should mention that just as I was posting, because the tunnel between Kidbrooke and Blackheath was similarly built because of a landowner not wanting the railway.
Does Bromley South count - the main A21 goes over it half way down in a small tunnel (or does it only count as a bridge)?
