If you’re a train buff or enjoy seeing history, you’re invited to 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 during a 13-thousand mile, 15-state tour. No. 844 will be 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. After it leaves Timpson, the locomotive is scheduled to be in Lufkin Thursday afternoon for an overnight stay. The No. 844 can run up to speeds of 110-mph, but according to Union Pacific officials, they do not run her that fast. The train is more than 114 feet long with a water capacity of over 23-thousand gallons and weighs more than 454 tons. The No. 844 has made appearances at Expo 74 in Spokane, Washington; the 1984 World’s Fair in New Orleans, among other historical events. The locomotive is scheduled to arrive in Houston Saturday.
