Hello You're right, I have left the TTD community quite some time. At that point I did not care, and it did not seem importatnt for me to license any of my work, since it was a fairly closed community. The fact that after all this time the project still is under development is really pleasuring. Additionally you're right, I need some licenese attached to allow the community to benefit and build on any of my work. So hereby I licenese all my work (including any that were not named below) under the http://creativecommons.org/licenses/by-nc/3.0/ license. Mind you I was merely a coder, the artwork in most cases was someone else's, so you may need their licensing too. For the below mentioned three cases: The fences artwork is by Purno The new bridges artwork is mostly by Purno too, with the exception of the on/off ramps and bridge support sprites The trafficset artwork is 99% by Andrex, I only made some minor changes to the graphics and coded them together. Additionally I remember coding some of Purno's train graphics, namely a TGV and a BZVMot, and contributing to the japan set coding. Best regards and good luck for your project, Szappy
