Two Locomotives Working on Same Lead Track

In Exhibit Q-9, two yard locomotives are working side by side on the same lead track. The engineer on the locomotive on the left cannot possibly see the locomotive on the right of the picture because of the hood of the locomotive and the engineer on the locomotive on the left must and does, therefore, rely on his fireman sitting on the left hand side of the cab, to observe such other train movements in the yard. Note also in this picture the extreme track curvatures in all directions, both in the left and right hand portions of the picture.
