This Video takes a look back at Trains Through Spalding before the Joint Line was upgraded for the regular Freight trains we have today, it shows a mixture of Steam & Diesel, I hope you enjoy watching.
Each power car (there is a DMBSO at each end) has an EE 4SRKT power unit of 500 hp. If you stand mid-train, therefore, it's equivalent to a 20, but in really good stereo!
