I came across a very old set of articles about the origin of C151 that were very interesting. It has not brought up for a long, long, long, time, and it has nothing to do with technical specifications either, so I'd want to make it a quiz so that others can have a guess.
In 1984, a Japanese consortium consisting of Kawasaki Heavy Industries, Nippon Sharyo, Kinki Sharyo and Tokyu Car Corp were awarded C151, and the rest we say is history. But back then, in a market where rolling stock companies are begging for orders and some facing serious finanical problems, this contract was fought over with tooth and nail by companies around the world. The unprecedented size of the initial MRT system meant that winning it could fill the ricebowl of the company for many years to come, and could use Singapore as part of their track record when bidding for future contracts elsewhere.
There were 8 bids for the C151 contract. Later, it was shortlisted to 3 before the winner was announced in Apr 1984. Here's the question.
And something to think about : Imagine if either of the other two finalists were chosen. How would our trains have become today?
