In 1870 a route was surveyed from the Boston and Albany Railroad at South Spencer to the center of the village. The issue was brought to a town meeting in 1872 where the idea was voted "to pass over the article." Various other surveys were now made covering this and many other routes. It wasn't brought up again until April 7, 1877, where the article was passed over once again. After several other meetings on the same subject, the town finally, on April 3, 1878, voted to spend approximately $25,000 on building the railroad. In 1878, a 2 1/4 mile railroad was built, connecting Spencer Center with the Boston-Albany Railroad at Spencer Depot NE with the station being at South Spencer. After it was decommissioned and removed, it was tuned into Depot Trail. It now connects Chestnut Street and S. Spencer Road.
In order to find the information to solve this puzzle, you will have to do some googling. I used 2 websites for my information, one for the first part and a different one for the other. Of course it wouldn't be googling if I gave you the websites. So I compiled some information that you must complete
