Each     sub-class     has     it's     own     diagram,     detailing     overall     dimensions,     horsepower information,   railway   assignments   (i.e.:   CN   or   GTW   etc.),   truck   types,   number   of   fans, dynamic   brakes,   steam   or   electric   generators,   roof   top   air   tanks   on   GEEP   units,   max. speed, max. operating curve, and on and on.  The   data   diagrams   are   cadd   drawn   reproductions   of   the   original   railway   sheets   and   the data portion is a clean typeset of the original. Find   out   when   trucks   were   changed   from   four   to   six   axle   or   vice   versa   and   back   again. This   is   an   excellent   reference   when   trying   to   date   photos   where   modifications   have   been recorded on these data sheets.
