Major train accidents resulted in no casualties Two, without exaggeration, grandiose train wrecks occurred in less than 24 hours in the Voronezh and Ryazan regions. In one case, a collision between two freight trains derailed and mangled more than 40 cars carrying, among other things, hazardous chemicals. As a result, about 20 tons of hydrochloric acid spilled onto the ground. In another case, a trailer carrying an excavator damaged a railway bridge, onto which a train soon arrived.
