By innovatively adopting this method for the first time on six grade-crossing eliminations in the United States, the project team was ahead of schedule. 鈥淚t’s a huge leap forward from how LIRR traditionally does grade-crossing eliminations,鈥 according to Anthony Tufano, executive director of the mainline expansion project for LIRR.

As one of the busiest commuter lines, LIRR has 126 stops crossing Manhattan, Queens, Brooklyn and Long Island, providing transportation to the entire metropolitan area in various capacities. Phillip Eng, president of the LIRR told ENR: “I don鈥檛 know if you can find another commuter railroad that has this many grade crossings in such a short geographical footprint. I would absolutely recommend [the box-jacking method] to others. If it works for LIRR, it鈥檚 going to work for other railroads across America.”
