Thanks for the comments lads, they are very much appreciated I'll try and answer the questions asked below:
1) The layout is still very much a work in progress! I'm in the middle of doing a civil engineering masters so time is unfortunately very scarce, as many on this site can relate to, and so I haven't really made much progress since I posted up photo's before which can be found here http://irishrailwaymodeller.com/showthread.php/1043-Barls-Layout
2) The grass is simple Noch long static grass from a puffer bottle over a layer of cheap mix of 'saw dust' scatter from the likes of Hornby and Noch. I tried using a static grass applicator I got from ebay but I found the puffer bottle to be much easier and to give better results! In some of the embankment areas a layer of hanging basket liner is placed under the static grass but I'm not sure if this really adds any depth to the scenery?
3) The layout is DCC operated and wired all over. It is controlled from a Hornby Elite controller, which many people would recommend you avoid, but I have never had any issues with and it does the job perfectly for a layout of this size! The points are operated using standard switch and CDU control.
Hope this helps
