TRS, any version, will pick the last update stream you updated from. This is pretty mild compared to other software that goes to the last save location and we end up constantly navigating in the explorer window to where we want the data to go.Trainz is a full mystery: today I made a new installation of Trainz Plus via the full offline installer (build 131950). Then, with the stream set as "Trainz Plus" by default, it said "No updates available". I had to modify it to "Trainz Plus Beta" to get to 132284.
