Paul, I wonder if you can help with a couple of items?
First, several 1500/1600 units appear to have a vertical
pipe running from the hood to the front number board
assembly ahead of the windshields, what purpose does it
serve? http://tinyurl.com/yhvgkba

Second, what are the contraptions on 1602?

Thanks!

As far as visual differences on the rebuilt units, here is a few items
to look for. As mentioned before, units received a chop nose with an
SD40-2 number board assembly and a low hood bell applied at this
location. Units received SD40-2 style sand filler hatch covers. The
fuel tank skirts were removed. One of the most significant changes
(besides the chop nose) is the modification of corner steps to the
vertical style as used on Canadian built GM units such as the GP30,
GP35, GP38, GP38-2, SD40, SD40-2. Also, all yard units had the dynamic
brake equipment (blower, grids, and switchgear) removed. After the
first 2 dozen (?) rebuilds, the dynamic brake grid air intakes were
blanked off externally which changed the appearance of the units. The
CP 8200 series road engines retained dynamic brake capability.
The yard units retained the straight pilot and foot boards (later
removed) while the road units had standard CPR curved steel "rock
pilots" applied as used on units such as CP GP38-2's.
The yard units were re-classified to DS-15 (GP7) and DS-17 (GP9) units.
(DS = Diesel Switcher)
The road units were classified as DRS-17 (GP9) units as before rebuild.
(DRS = Diesel Road Switcher)
Hope this helps.
