Jackson Michigan Railroad Depot built in 1873, (the original Jackson station was built in 1841 ) might be the oldest continuously operating train station in the US. It has not seen a single lapse in service once in its history

One interesting aspect of the station is its slate roof. The hard and inflammable slate was used so it was more protected against fire from flying sparks from the wood and coal burning steam engines of the late 1800s.
