[/quote]Another spotting feature, though not always accurate, is the style of radiator grills on the side of the long hood. SD40's had the chicken-wire flat grills...40-2's have the raised ribbing.... Dave Williams http://groups.yahoo.com/group/nsaltoonajohnstown <br />[/quote] <br /> <br />Actually, early production SD40-2s carried over the chicken wire grills, corregated grills were phased in in the mid-70s, along with other minutae like anticlimbers and 88" noses. The truth is, after up to 32 years in service, spotting on the fly is a nightmare. I am a reformed rivet counter myself, and if see an SD40-something go by, I am happy to call it an SD40 in the field. In the same way, I just talk about 'geeps' and 'switchers' to discuss 1949-1961 and 1939-1966 production respectively, the parts by this time being so scrambled that arguing over models, much less phases, is pointless. <br /> <br />Just know what is 'normal' so you can spot oddballs, then go home and look them up. Of course then the 'experts' can't decide whether a 16 cylinder SD45 rebuild is an 'SD40-2' or an 'SD45m' themselves, so just do what you need to to get your point across. <br /> <br />Roger Rassche
