"The brake valve!"
Upon hearing his words, Evan was thankful for the distance between the cars and the fact that the intercom was not on, or the amount of panic caused by this short 'conversation' would have been unimaginable.
The Driver quickly ran back into his cab and quickly pulled down a red lever that had a similarly coloured large caution sign printed right beside it, but even after holding it down for more than 15 seconds, he saw that the train's speed was not reduced in the slightest.
He quickly let go of the emergency brake and grabbed the handheld radio in the cab before pressing a button and screaming into it.
"MAYDAY! MAYDAY! MAYDAY!!!"
Evan let the man handle the official procedures while he moved to check on the motionless engineer on the floor to be sure he still drew breath.
At the same time, he was wrecking his brain for a method that could be used to either slow down or completely stop the train that was currently going forward at full speed.
