I have recently started using Trains 2006 collector's edition. Where I live, I don't have space for a large model railroad, so using the simulator software is very handy for me. I especially enjoy the interactive industries, and working with waybills. I really like the "extend world" feature, which allows me to expand my world, and create huge worlds. Has anyone got any tips for surveyor mode? happy modelling to you all, cheers Axledanda
