[QUOTE]Originally posted by Gilbert B Norman: [QB] After reviewing this material appearing in Today's New York 'Mini' Times (today they adopted the 12" width format of most other papers), I am lead to wonder to what extent it is possible to estimate the load on a highway bridge at any given time? http://www.nytimes.com/2007/08/06/us/06collapse.html Railroads are not confronted with this problem, as the weight of any train is known. Railroads can and do restrict the weight of trains on bridges. Case in point is the Kate Shelly Bridge in Central Iowa where even though double tracked, only one train may be on the bridge at any time. Of course, for those around here who contend that UP is letting their property "go to rack and ruin', it should be noted September TRAINS has an article stating how this bridger is being rebuilt so that two trains can be accomodated simultaneously. http://www.hdrinc.com/Assets/documents/Publications/RailLine/june2007/KateShelley.pdf [/QB][/QUOTE]
