Mate you need more info for it to be a proper suggestion as short suggestions with barely any information like this really makes me yearn the days on this suggestion forum when we had the how to and not to write a suggestion thread pinned at the very top of the forum. As without it short suggestions like these become more common unfortunately. Also to the OP details like mileage, country, interest, reasoning etc are all what make a suggestion great. Next time try looking at suggestions by some well-known poster which have great suggestion I used for some of my TSW suggestions such as elarthur, edward#5859, trainsimplayer, TrainGeek08 and etc.
I don't think we need much detail on this one. It's been suggested enough times in great detail. We don't need to know anything about the route it will go on as that's pretty obvious, at least to me (the current ECML route being the candidate). There's plenty of interest and quite a few want it in TSW, going by many other threads.
