Two units at DBR: GTW SD40-2 5936 has been the assigned power on Canadian National's L507 job for a little over a month, but due to a number of little concerns, needs to make a trip to the shop. Earlier today, WSOR delivered the EJ&E 663 to DBR Jct., spotting it on the WSOR/CN connection. In this photo L507 has just tied up, placing its GTW unit nose to tail with the replacement power. The next WSOR job will pick up the GTW 5936 and deliver it to CN interchange at Ackerville. L507 will go to work Monday morning with the EJ&E locomotive.
