Posted by Concourse Express on Mon Mar 8 19:22:58 2010, in response to train speed over Manhattan Bridge., posted by rbseabeach on Mon Mar 8 18:48:42 2010. Is there a specific reason why the trains go so slow over the bridge?On the Manhattan Bridge, you have 25 mph grade timers on the decline in both directions on both sides; the need for timers here probably has to do with minimizing bridge flexing and swaying caused by passing trains. my blog |
