Not at the moment.
The worst kept secret in the world is they want to extend service X4 down to Whitby every half hour from Easington to give a coastal Middlesbrough-Whitby service via Redcar, Saltburn and Loftus in place of service 5 which would be curtailed at Easington. Several surveys have been taking place on buses over the last few months with regards to this.
There are 6 consultations being distributed on bus as well as these online versions (I've collected 2 so far...) which should help shape service changes in February 2014.
