Reason for quick discontinuation?
I wonder why this train was only in construction for one year. 4 sets ever constructed seems an awfully low number considering the massive design and manufacturing overhead that must be involved in creating a new model. Were there maybe technical difficulties with these trains, or some other unforeseen reason why they would've been discontinued so quickly? 188.63.151.199 (talk) 23:10, 2 January 2015 (UTC)
