Well, it’s been several days and nobody has ventured a guess, so I’ll just offer the answer now. The most-written about news story in the Webster-Kirkwood Times from 1986 to 1988 was the shipping of radioactive waste from the Three Mile Island accident on trains through St. Louis County to points west where that waste was to be disposed of. Those shipments came through Webster Groves on the Missouri Pacific line.
Three Mile Island, a nuclear power plant in Pennsylvania, experienced a meltdown in March 1979, creating a lot of contaminated water, soil, and nuclear waste. The cleanup lasted until 1993, and it seems that nobody whose communities the waste passed through was happy about it. Residents in Webster Groves, as you may imagine, had a lot to say about it, and every local legislator worked to end the train shipments through town.
