Class 45

Best fuckin diesel out there. Sadly they are marmite engines, you get the sensible people that think they are hellfire and great engines, then you get the shitheads who wank over class 37s saying how shit they are.

37 basher: DO 1 SHITY PEEK OW CUN U LIEK THOWSE M8 THAY R SHIT
Peak basher: Cus they are hellfire you deaf twat, go back to wanking over EE and leave the sulzers to the real men.

If you dont like the sound of a class 45, please get your ears tested. Or you just go round chasing 37s and hate anything that isnt or doesnt sound similar to a class 37.
