Now TRAIN CLIP, is sometime required for any% run. Train takes about 30 seconds to arrive, so cutting that sweet, sweet, seconds off is really needed. However, its a really complicated process and it takes a while to do it right one time, but due to it being an inconsistent glitch, there are some runs where you wont be able to do it. So, how do you train clip? First put yourself up to the right window on your screen, back to it, and hold down s. Heres the place you should be (https://imgur.com/bBDGz3g) and then you should hold down s and start spam jumping and crouching and if your lucky, you should be clipping through the window.

Edit : That is now the old legacy edition which still works, now theres a new method in town. You hold down your minimize button when gman says "Wake " until the horns go on, then you immediately clip out, thanks Mally for finding the method.
