The key word he used was 'standard gauge.' That basically means he intends to redo the entire network, engines, rolling stock etc.
Laudable, KR have been saying the same thing, so WR will continue something that has been set in motion.
What really impressed me was the ipad he used, a marked difference from your ordinary politician who uses the back of the event programme to scribble notes on.
He made a specific promise, good move but it wasn't SMART (specific, measurable, achievable, realistic, time bound).
