Nielsen Library will host Jim Poston speaking on the history of Locomotive 169, the train under the pavilion at Cole Park in Alamosa, Colo. The event will begin at noon on Wednesday, Nov. 6, in the Nielsen Library second floor lounge. The event is free and open to the public and light refreshments will be provided.

Poston is a longtime volunteer with the Friends of the 169, a local group dedicated to preserving locomotive 169 and, eventually, restoring it to operating condition. He is originally from Rhode Island and worked for NASA until 2000 and now resides in the San Luis Valley.
