The feed is coming from a radio about 2' from the computer I'm typing this on (right here in Hamlin, Les).
The radio does quite well - being so close to the lake, CN and CP are usually booming, especially at night. When the conditions get good, reception can get ridiculous - I was hearing trains calling signals on the Lake Shore Sub from CP-2 all the way to Ashtabula the other night, and the night before that, was hearing trains on the entire length of the Mohawk Sub.
I've had the radio setup and stream for a while now - but it was only recently that I went public with it. It's scanning quite a bit of stuff, and it can be quite a challenge to keep up with all the chatter sometimes, but I still enjoy it nevertheless.
