Just a quick note to let you all know I have uploaded a new and improved version of Blender Train. You can now haul coal up the hill to keep the power station running. It has new scenery, sound FX and motion logic as well as a new brake system and an early switching system to test.
It can be downloaded from http://www.bentstraight.org/thetrainpage.html
There is a windows exe version as well as the blend file for anyone who wants to take it further. Any tips , feedback or comments are welcome.
