[originaltext] A Continental Pacific Railroad goods train derailed (went off

A Continental Pacific Railroad goods train derailed (went off the tracks) on Tuesday about 40 miles north of Sacramento. The exact cause is still being investigated, but authorities say it was no accident. The head engineer said everything was fine; then suddenly, everything wasn’t.
    Of the goods train’s 86 cars, 22 went off the tracks. Fortunately, this incident did not involve any deaths, human or otherwise. The head engineer was treated for a broken wrist at a nearby hospital. He was the only injured.
    Trains throughout California frequently carry dangerous goods, such as chemicals. When these trains derail authorities immediately evacuate nearby communities because of the danger of explosions or of harmful fumes. However, this train carried only lumber, new automobiles, and cattle destined for slaughter.
    After the derailment, lumber was scattered on either side of the tracks. About 20 automobiles were damaged. The biggest problem, however, was the cattle. About 300 of them were standing on or near the tracks, wandering into the nearby woods, or standing on the nearby highway. Traffic on the two-lane highway was backed up for almost a mile in each direction. A California Highway Patrol spokesman said that they knew who was responsible for this. The train was damaged by a group called Tofu for You. They left their pamphlets all over the crime scene. They "liberate" animals that are on their way to the slaughterhouse. They think Americans should eat tofu instead of meat, but their effort was in vain. All these cows were killed and became burgers three days later.
