One of the features I miss most in TSW is the ability to export train location information to third party mapping programs. ThirdRails started out as aprogram that let you track your progress on google satellite maps or simular type services I found the experience not only enjoyable but educational to see on the real world maps where the routes were located, what the terrain actually looked like and learned a bit more about the geography of the different countries. I read a rumor that DTG Matt was contemplating working on an API, and if this rumor is true - would campaign to make the gps position of the locomotives visible so such a program as ThirdRails would be a possibility for TSW
