Universal, stackable Piers for Unitrack & Viaducts

Here's a new version of the piers for KATO’s track systems (n-scale). The goal was optimal stability with compact storage, as well as the ability to use them not only for viaducts but also directly with Unitrack track. Especially with temporary layouts, you don't always have viaduct track available, and it's not exactly compact to store as well, isn’t it. By that reason there are two adapters, to be inserted into the pier, one for viaducts (you need the S-Joiner here) and one for tracks fitting into the track bed. So, you can even combine viaducts and track, if adjusting the height, for what there are another kind of adapter is available. However, when using the tracks only, there is a risk that the trains could fall off the elevated rails. To prevent this, there are holders into which cardboard strips can be inserted. These can then be rolled up for transport/storage. Another issue is that especially for ramps a fine tuning of the hight may be necessary. So, I created some more adjust
