According to your logic, with so many pending changes and unknown details about CR151 and by creating that page, what about CJ151, C851E etc.? I purposefully deleted and remove those page because nothing had been finalized. Not even an actual train set had been manufactured. How can we be that sure? Just like how bus models page was created after the first vehicle come into registration, train model will follow the same, with page name (future) being listed instead of hyperlink or created.
