Loading ...Good Grief! You are lucky to be alive. Carbon Monoxide poisoning is the usual cause. Also the cause of the long headache. It takes a long time to clear out of the body. Brain Damage? Maybe, but you are still with us.
Tunnel air also affects the performance of the diesel engines when they cannot get enough oxygen. The Rio Grande, because they had so many tunnels thru the mountains in their system, ordered special locomotives. They were called ‘tunnel motors’. The air intakes on the body were at low level by the frame instead of on top, where they could suck exhaust. The ‘tunnel motor’ design sucked intake air from a lower mid-level. Many are still around today. The design is the SD40-2T.
