Yards are generally boring..unless you like watching freight cars sitting around. There are 2 decent sized manifest trains that are made up over the hump and head out of Buckeye yard in Columbus each day and head up to belview Ohio and get re routed from there.... usually 100 to 140 cars... Thats all I know about.. i dont even know the train symbols anymore for NS ..I use to know it all when it was Conrail.. BESE ( Buckeye to Selkirk) and then there was one that ran to Buffulo... and the BEEL- (Buckeye to Elkart)
