Just saw on the webpage that the LIRR was allowing heavier loads. Has the inbound shipments of construction mat. increased? What about the outbound debris?
What webpage? They have a weight restriction of 263,000lbs per car and any car over that limit would have to be specially approved by the Engineering Department. To go to 286,000lbs (the now-industry standard), engineering would have to shore up the entire infrastructure to comply before signing off on the additional weight. That can't happen due to a storm, and would not happen overnight.
Construction debris will most likely increase in the area due to the storm. However those loads generally cube out before they weight out anyway.
