The report also noted that although the front-end and rear-end crews should have been in regular communication, that did not appear to be the case in this accident. As the freight train reached Hargwen, Engineer Hudson radioed back to Conductor Smith that the signals were green, a communication that was heard by a following freight. As it ran towards Dalehurst there was no evidence of further communication. The conductor is in charge of the train, so if Smith felt that the train was out of control or there were serious problems, he should have activated the emergency brake in the caboose to stop the train. However, Smith, who appeared to be nervous while testifying, said that he did not feel that the freight was ever out of control, misjudging its speed. He also testified that he attempted to radio Hudson on two radios and several channels, but neither seemed to be working, even though immediately after the crash Smith was able to contact the dispatcher by radio. Despite Smith's testimony, he apparently decided not to stop the train.
