A real easy way to commit suicide (statistically most effective) is a train track, lay so your neck goes over the part where the wheel rolls and it will literally decapitate you. I'd suggest getting wasted and downing a bottle of sleeping pills first, and wear a blindfold or something, so survival instincts don't kick in and put you in a wheelchair. You're gonna wanna be away from the station (so that the train is at high velocity), and you want to minimize visibility (dark clothes, nighttime if trains are running, in a bushy area etc). It also might not be a bad idea to get tons of drugs to make sure you can't come back from it.
