If you heard a "chug chug" and a different sounding train whistle through Sacramento this morning, you were most likely hearing Union Pacifics UP844 passing through in route to Oakland. We caught up with UP844 passing over the I street bridge coming into West Sacramento. Within the past hour, UP844 has passed through Benicia where the train was greeted by large crowds and signs as well as being paced by a news chopper through Emeryville. If you missed this historical steamer, you will have a chance to catch it again as it comes back through in the next few days. See schedule below or go to www. up.com and search UP844.
