Two things interesting about this middle Union Pacific Unit. First &emdash; SD40-2 unit B4232 has had its cab equipment removed and esentially fuctions as a cabless "B" unit. The Second is that this unit is displaying “North Little Rock” lettering &emdash; quite a double rarity. The NLR lettering was mainly applied to ex-Missouri Pacific units, which accounts for the lack of the characteristic dynamic brakes on this engine.
