Rather than try to extend my Plasticard station platform, which is on a curve, I reckon it's going to be quicker and easier to just build another to the required length from scratch. Rather than use Plasticard again, I've found a couple of suitable bits of green (moisture-resistant) MDF which I can join together to get the length, and I've even found a couple of new jigsaw blades for the cutting thereof, so I'm all set except for one aspect. When you guys make platforms from MDF, what do you do about the ramps on the ends?
