Strangers carried her and her wheelchair, which weighs more than 200 pounds, to an empty tunnel tube, where she could wheel to Brooklyn.

There are 3 passages connecting the two tunnel tubes, accessible on foot.

The second tunnel tube was excavated in August 2007 and opened to traffic in 2008.

"I built the tunnel tube from a plastic material and it emitted green and yellow hues."

Construction on the existing tunnel tube began in 1978 and it was opened for traffic on September 27, 1981.

Two parallel tunnel tubes were cut through the mountain for the double-track line.

Since the first tunnel tube was already in use, traffic had to be suspended three times a day to allow progress of the works.

At each of those times, traffic through the first tunnel tube was suspended for safety reasons.

Every 250 metres, the two tunnel tubes are connected to each other by lateral connections.

Konstruktor completed the construction of the first tunnel tube by June 2003 and the second one in June 2007.
