drodder - I took the video with my about 5 year old Sony Cyber-Shot digital camera. It's is getting a little dated, but still takes decent pictures. The limiting factor is the guy taking the pictures.
Thanks for the comments on the interchange track. My biggest challenge was limiting the grade on my two interchange tracks to 2%. IN fact the other interchange is 2 1/2%, but close enough. That enables me to run any train that I run up or down either interchange track and enhances the operational elements. I am in the process of adding sidings and industries so we can have more realistic operating sessions involving setting out cars at businesses and working them back into first a regional yard and ultimately back to Proviso.
The second interchange track enters my passenger dominated mainline with traffic flowing the opposite direction as the freight mainline. That in conjunction with my series of crossovers allows me to bring trains up or down in either direction to either lower mainline.
