TOPEKA, Kan. (AP) — Heavy rain has washed out several sections of railroad track, damaged a small bridge and caused about 2.4 million gallons of untreated wastewater to be released into the Kansas River. The Topeka Capital-Journal reports that the heavy rains fell from Monday night through Wednesday morning. Union Pacific spokeswoman Calli Hite says the rains washed out multiple small sections of track in Shawnee County. She says water also damaged a small bridge near Willard. Hite says Union Pacific doesn't have an estimated date for reopening the track, and the extent of the damage remained unclear. The rains, along with a mechanical failure, also led to a sanitary sewer overflow in Topeka. City spokeswoman Aly Van Dyke says the rainfall caused higher than normal wastewater and stormwater flow volumes.
