390 

This is the police code for "being" drunk. 502 is the Code for Driving drunk. Same thing but depends on what you're doing. May 2th still stands as Drunk Day, no matter what though.

1: Look he's pulling a 502!
2: No, stupid, he's not driving. That's a 390!

390 

Ford Big Block. Simply one of the best engines EVER made. It was put in cars and trucks from the late 50s to early 70s. Some other members of the FE family are the 352 406 428 and the most revered 427 side oiler.

My 390 put up with 2 years of nothing but shit and she stills purrs like a champ.

student: ....fuck CUPE 3903. They're such fags.

Pretentious bastards who screw students out of their time and money buy kicking them out of school. They like to extort the not-for-profit york university for millions of dollars during times of economic crisis causing the whole system to shut down.

Father: "Son, how come you have to stay in school for an extra semester before graduating, causing you to miss out on half a years salary of your life?!?"

Son: "CUPE 3903 screwed me out of school so i couldnt take second semester because i had to work to pay tuition"

Father: "Those bastards"

3901 Cupboard

A well known cupboard inside a Class 180 Adelante train, inside which are several buttons and switches which control the engine.

The infamous Paul Tyreman has starred in many railway safety videos, and over the past decade railway fans have created lots of YTPs of his material. Just search "Paul Tyreman YTP" on YouTube!

Looks like the engine is not working, better check the 3901 cupboard
