A Manhattan straphanger has received the MTA's "highest civilian honor": free rides for a year. Rikien Wilder, caught the alleged culprit who caused a train derailment Sunday.

Wilder was standing on the 14th street platform when he heard the man putting metal debris on the tracks. He quickly hopped down, removed it and ran to alert an MTA worker. But when he returned the man was at it again. That’s when an A train derailed.

“It kind of angered me a little bit because he seemed to get some joy out of wrecking the train,” he said.

So he chased the man and grabbed him right before he reached the turnstile then kept him in a chokehold for 15 minutes until police arrived. He sprained his wrist in the struggle.

The man faces several charges including assault and criminal tampering.

MTA officials gave Wilder an oversized metro card at their monthly board meeting and called him a subway hero.
