Posted by Jersey Mike on Wed Nov 7 00:20:09 2007, in response to PHOTOS: B&O/SEPTA Route 11 Darby crossing, posted by chuchubob on Tue Nov 6 21:55:44 2007. How does the trolley not derail? There is nothing preventing the flange from deviating from its path along the rail.That is the new speed restriction that the trolleys have there. I have heard that those types of diamonds are only good for about 5-10mph. |
