A childhood friend of mine can drive a train. He joined Mumbai Metro as a Locomotive Pilot but has now moved to a different capacity within the same undertaking.
Some months ago, I helped him learn the ropes on his uncle's Splendor for the very first time. He did good that day even though it was his first experience riding a bike. Haven't had a chance to practice again since then. Basically, he learned how to pilot a train before he did a geared motorcycle.
