Actual running time was 1h 24m. Took me a bit longer than normal as it was the first running session of the season and so distributing the goods stock to the outlying stations took longer. Normally, the goods stock is stored in blocks on the storage sidings according to their old locations and so the distribution goods train is ready made up. Also, I don't need to brush the station areas quite so rigorously later on in the season. Setting-up for a full operating session usually takes between 40m and an hour.
Of course, when I just fancy running a train or two, it takes a lot less time to set up (just a quick trip around the line to 'tame' the plantlife).
