Railroad officials say four cars carrying sulfuric acid and ethanol that are derailed in Hermon don’t pose a danger to the public because none of the liquid has leaked.The cars from Montreal Maine and Atlantic Railway derailed about 8 o’clock yesterday morning behind LMS Transportation. That’s in an industrial park off Cold Brook Road in Hermon. John Schultz, the vice president of transportation with the railroad company, says crews continue to make repairs to get the cars back on track. Three of them contain sulfuric acid, one has ethanol. A hazardous materials team is on site, too, while workers off-load acid from two of the cars to make the job easier. The Hermon fire department is also on the scene as a precaution. Schultz says the train was on its way to customers in Searsport when the cars left the track. He says the cause is under investigation and the re-railing work should be done by tomorrow night.
