Since completion of works on the signalling upgrade in 2011, LU has incrementally increased the frequency on the line to the 30 trains per hour that operates during peak periods today. The modernised signalling allows LU to run trains more reliably and more frequently. It also allows trains to reach a faster top speed, although at this location trains run no faster than previously as they are accelerating from or braking towards Baker Street station, and are not running at maximum permitted speed. There has also been no change to train weight.
