Sadly, because light gray is the only color risers I have the yellow caps would not look right. Like ActionChugger I would purchase a large lot of them too most likely much more than 50 if they were easily made in gray also but I understand the need for more interest to make it worth their time and material. I am curious as to why he decided to make them in the dark gray as in the Plarail Advance colored risers as these caps do not look to work with the Advance trains. The lip that holds down the track would get in the way of the train passing by this is why the tall dark gray Advance risers have no lip where the tall yellow risers do. I do appreciate your looking into this for us Plarnold and for your friends time too!
Thanks Plarnold for taking the time to make us the video. I can't wait for all my light gray caps to arrive.
