A part of history will be in Timpson Thursday morning when “No. 844” will be making a service stop en route to Houston for Union Pacific Railroad’s 150th anniversary. No. 844 is the last steam locomotive build for Union Pacific, and is scheduled to stop in Timpson at 11:15 Thursday morning, and is expected to be there for about 30 minutes while crew members service the 68-year old engine. Everyone is invited to come out to see the locomotive.
