Caption: GT 4520 was the last CN GP-9 left with the high short hood. It has roof mounted air reservoirs which on passenger Geeps had to be relocated because a water tank was added under the frame for a steam generator. It was brought to Edmonton complete and in running condition. Over the years, the number boards, horn, headlights and bell have been stolen off the locomotive. Before being donated to the museum it could be seen in the dead line at Walker Yard.
