Regarding scales and gauges, EM gauge stands for "eighteen millimeters", equivalent to 4' 6" in OO scale. Modern EM gauge is 18.2 millimeters (4' 6.6"). P4 is 18.83 millimeters or 4' 8.49". In S scale we have had a little less controversy. The traditional 7/8-inch is 4' 8". The current NASG standard is equivalent to a minimum 4' 8.5116" and a maximum 4' 9.9204". There's a nice discussion of various scales, including S, on the Web site of the Abingdon and District Model Railway Club: <http://abingdonmrc.org.uk/about/model_railways/sgscales.php> -- Bill Roberts, Receiver San Antonio & Aransas Pass Railway Co. * * * Notice to travelers * * * Bicycles, baby carriages, dogs and guns are transported in baggage cars subject to tariff regulations.
