At 8 a.m. today, the historic Union Pacific steam locomotive 844 will move through Sacramento in route to Oakland where it will be on display. The Steamer has been in Roseville at the UP Yard for the past couple of days. Saturday, UP844, along with other UP locomotive memorables were on display for general public and Sunday they were held for a private showing accessed only by UP friends and family. If you are looking for good photo ops to catch old UP844 puffing down the tracks, it will roll out of Roseville and will be highly visible through the wetlands near CalExpo, You should also be able to see the puffer rolling through the downtown Amtrak station and over the "I Street" bridge.
