BN 2550-2566 series of ex-Frisco's 'Torpedo Tube' GP35's... does anyone have any overhead rear shots or diagrams that show the routing of the airlines? There is a couple of images taken from ground level that show the airline disappearing into the rear right end just above the numberboards but none higher up showing the left side. Also, the positioning of the air tanks themselves either side of the dynamic brake fan. The fore/aft positioning is reasonably well documented with images, and the drawings on Michael Eby's site, but the side-to-side spacing isn't. Thanks in advance for any information.
