color:#1F497D'>This is all from memory………..Unlike the normal
practice with" single" cab control, the long hood was designated
front (there are plenty of instances where single cab control was setup with
long hood front too). Unlike the N&W prior standard of buying all new
units with "dual" cab controls (2 control stands in the locomotive
cab, one on each side of the cab, one facing long and one facing short hood
lead) these SD-40-2s had a single control stand on the right side of the cab (as
orientated looking forward down the long hood with your back to the short hood).
(If I can recall from being in these units, many years ago, the control
stand was oriented a bit differently than normal to facilitate bi-directional
operation.) As such… when running long hood lead the control stand
was on the correct side of the locomotive for the engineer to view the road
ahead and signals . If the locomotive was to be run short hood lead
(unlike with a high short hood) the engineer could view the road ahead and
signals by turning and viewing them through the windows and over/across the low,
short hood. N&W called this arrangement "bi-directional" cab
control. The reason was simple; economics. First N&W wanted to
save capital in not purchasing 2 control stands and associated hardware with
each new locomotive. Also by having one control stand (as opposed
to 2) it would in theory reduce associated control stand maintenance expense for
the locomotive by 1/2. Additionally the locomotive cab now had additional
room for crew members. All the units purchased by the N&W up until
these 1600 series SD-40-2's including the T-6's had "dual" cab
controls. <o:p></o:p></span></p>

were purchased with single cab control (most were short hood front/lead…seems
there were exceptions like the H-20-44 FM's and the NKP Baldwin's that were
rebuilt by ALCO and EMD). The "First and Second Generation Diesel"
books give this information for all units.<o:p></o:p></span></p>

<p class=MsoNormal> In Russ Goodwin's e-mail's second
paragraph he says that the Highhood have the short hood as the front and the
low hoods have the long hood as front. Any ideas as to why the high hoods
weren't ordered as long hood forward?<o:p></o:p></p>
<p class=MsoNormal><br>
The high hood N&W SD40-2's *were* setup with dual control stands and the
long hood designated as the front. The only N&W SD40-2's setup for
short hood forward operation were the units in the last order, Nos. 6189-6207,
which were also the only N&W SD40-2's setup with single control. All
of the other low short hood SD40-2's were equipped with a bi-directional
control stand with the long hood designated as the front.<br>
