OAKLAND (CBS SF) — Ever notice how BART trains slow down on certain sections of track? They do that because the 40-year-old wooden ties are so old they could come loose at higher speeds, potentially causing a train to not only derail, but go plummeting off the elevated tracks as nearly happened during a 2014 derailment at one of the problem sections in Concord.

According to a federal report, tracks like those used by BART have an expected lifespan of 25-years, but most of BART’s tracks are more than 40-years-old.  Now, 15 years after that period, BART is beginning several closures to repair and upgrade the sections of track.

BART writes, “A switch (which allows the trains to be guided from one track to another) is in very bad shape, requiring trains currently to reduce speed in the area for safety. In addition, the wooden ties between the tracks are very worn out. ”

Many of the wooden ties are completely rotted out.
