Welcome to the temporary home of the Dell Blog. During our winter shut down we are continuing with our major project to divert the ground level 'Main' line from the tunnel it shares with the raised track. So we thought we would keep you informed with regular updates.
So why are we doing all this work? Answer is to move away from the shared tunnel. Sharing a tunnel is inconvenient for both tracks particularly for trains on the raised track. The trains on the raised track have to give way to those on the ground level track, to alleviate this we restrict the number of ground level trains which leads to a reduced capacity on both lines.
So if all goes well in 2017 we should be running more trains and carrying more passengers!
