I'm forced to mention you @StateOfMind lol
You need to stop doing this, I'm not an expert on train method lol
I was considering full suspension hanging, but I'm broke, thus can't buy any rope/belt
If you can't even afford a rope or belt then suicide may be a due option.
Some things to consider for decap.
Be aware aware of piping and other mechanical "anomalies" around the wheels.
"Cow pushers" or metal skirting on the lower end of the engine.
Train tracks are about one and a half inches wide, it's not going to be a "clean" cut.
You will probably still die but the last seconds would be pretty awful.
Do some trainspotting, figure out the train models (timing ect) and decide whats best. Decap, standing collision?
Hope this helps.
