A street in the Charles Village neighborhood of Baltimore collapsed Wednesday, washing away cars and flooding CSX railroad tracks that run below street level. Ian Brennan, a spokesman for the Baltimore Fire Department, said no injuries were reported.  One lane of the East 26th Street between North Charles and North St. Paul streets collapsed about 4 p.m. and slid down an embankment leading to the tracks below. The cause of the collapse was unclear, but it came on a day that the region was experiencing heavy rain storms. Several streets were closed late Wednesday afternoon. St. Paul and Charles are major thoroughfares that are generally crowded during both the morning and evening commutes. The neighborhood is largely residential row houses. Traffic was reported to be snarled in the area of the collapse and downtown. More
