EMC Winton-engined Switchers - 900 Hp (670 KW) N Series

900 Hp (670 KW) N Series

These locomotives were all nearly identical, except for cast versus welded underframes. The 900 hp (670 kW) V12 Winton 201-A-engined NC and NW series locomotives can be distinguished from the less powerful 600 hp (450 kW) SC and SW because, although the underframes are identical, the hood on the N series is longer, leaving only a small amount of room before the front walkway. Many, but not all, N series locomotives have a short electrical box with sharp-angled corners in that location; this is easily distinguished by the lower, longer, rounded-cornered "satchel" of the SC and SW series. The other distinguishing feature from the S series is the central location of the twin exhaust stacks; the S series have them offset towards the engineer's left, because of the inline diesel engine.
