As an instructor in Filipino stick and knife fighting (stick translates to machete), I can really respect the situation he was in. He handled himself flawlessly. He made no threat against someone robbing, which is not necessarily a threat to one's life or personal security. No sense throwing away your life over a wallet in most cases.
Then he stepped up when he had enough and saw the incoming rape.
Looking at it tactically, he had a good advantage in this situation of his position. Most train cars force you to fight very small numbers of opponents one at a time given the narrowness of the passageways. The distance of the rail car would be smaller, allowing easier distance closing. All speculative of course. I'm still amazed he pulled it off, but then again he is a Ghurka/Ghorka
Lastly "That's not a knife, THIS *pulls out kukri* is a knife mate", lol, I can just imagine :P
