Was quite looking forward to this release and even took today off work to play it. Although I can't fault the Class 20 I am disappointed that the (new) freight flow for the limestone hoppers is only (Redmire) from Eaglescliffe - Tees Yard. (Thought Darlington to Tess Yard was a pretty poor effort with the PCA's.) My 'interpretation' of the limestone workings was that they went to Redcar Mineral terminal. This is where they are shown in one of the teaser(!) images (although DTG do state these images are from Development work and may NOT reflect what is ACTUALLY available within gameplay). Still enjoying the Class 20, but based on expectation(!) the DLC in it's current form is only a 7/10.
The timetable mode is definitely a let down. It would be a great DLC if the timetable mode had a better collection of services The timetable mode has been a let down on recent DLC (204, M3 for starters).
