DRESBACH, Minn. — Authorities said an accident today involving two freight trains injured two people, set off a propane leak and caused some railroad cars to fall into the Mississippi River.

La Crescent Fire Chief Bernie Buehler said the accident happened about 5:30 a.m. near Dresbach, at the southeastern corner of Minnesota.

Buehler said two railroad employees on the trains were injured.

The immediate area has been evacuated because the accident caused a propane leak at a switching station. Winona County Emergency Management spokesman Dave Belz said liquid ammonia is leaking from some cars, too, but isn't a public danger.

Buehler said one train had 100 cars, and the other had 15. Some of the cars ended up in the Mississippi River. Crews could see fewer than half of the cars left standing.
