The clock in your picture was made by The New Haven Clock Company, in New Haven, CT. It is entirely possible that it is as old as you were told, although the company made that style until around 1920.
They were sometimes sold as advertisement clocks, with the name of a company reverse-painted on the glass, or dial. Many were sold as inexpensive regulator clocks that mimicked the more expensive box regulators of the time. There were also those sold as "store" or "office" clocks.
Going by your story, yours was obviously used as the latter. There is one peculiarity with your clock being in a train station. Most clocks of this type that were used in public places were time only. (no striking or chiming) This was so people could see the time but not be bothered by the noise.
Clocks of this type are generally valued at $300 to $1000. The higher prices for the clocks with advertisements on them.

I was able to find more information about your clock. The model looks to be the "Referee" made circa 1911. It was originally sold for $8.90 with a time and strike 8-day movement, or $7.40 with a time only movement.
The approx. value in 1997 by Tran Du Li is $400., although I see on eBay that they go for more now.
