Yup, it was. There are no sidings drawn on the plan so it is just the preliminary survey. I have to wonder if they would either have a freight interchange point where the FSK and MEC split just north of the station and passenger interchange would be handled by the streetcars, or if freight cars would be handled over the electric railway which was in the planning stages around the same time.
The path through Oakland is a little interesting too, which is forthcoming soon. I am in NJ this week for work (I am located in central ME) so updates will be slow, and the plans I found are incomplete so I have to chase down a couple more leads to see if I can get the rest of them. Also, I am inclined to believe that there is a rough sketch or description of the course from Western Ave in Waterville to the Kennebec River. If you look at google earth the land west of Messalonskee Stream from at least Kennedy Memorial Drive (Routes 137/11) to the MEC / Messalonskee Stream crossing was mostly farm land and undeveloped until the 1930's-1950's. The most significant buildings were probably located at the bridge over the stream on Western Avenue.
