What's going on here? Q: Is Union Pacific 4-8-4 844 being used in helper service, or is this a three-train meet? A: Three train meet. With congestion in Topeka and Kansas City, the 844 had to cool its heels in Paxico siding waiting for three westbounds. After a few hours, it crept across a rural crossing right up to the rear of an eastbound autorack train at MP 120. UP 9767 soon appeared around the bend with a westbound manifest. After the westbound cleared, the rack train took off, with the 844 following close behind.
