Caption: Chasing is always a part of railfanning...especially when you're into photographing trains and all sorts of railway related scenes. This day was no different. Except that a normally 'speedy' freight seemed to have a hard time gaining track speed. Here, with a replacement numberboard 8634 leads 8650 and a long string of gondolas across Third Line. For all of us who can remember, it brings back the 'yester-year' memories of the Alco's and MLW's who usually put on a good smoke show.
