AlisonW, I presume to ask you about two ideas for railmaps that I have very imperfectly sort of coded.
1) Britmax and I agreed that the usual way of joining two railway lines which cross at right angles and have a connecting chord was clumsy (that's with a 90degree turn off each line and a bulging 90degree corner filling the gap). I hope my very first SVG file (
) shows an improvement I thought of, I hope it's not too gross. Black lines are tile edges and red are tracks. It shows two ideas. Both need eight icons to make single starts or ends of diagonal connecting lines, and 4 bilateral start icons for points with both left and right chords. The left hand scheme runs through the common corners of four tiles and uses those fiddly little corner-filling icons which often use up valuable Overlay. The right hand scheme puts the diagonal through the edges of tiles with one (of four) icons to connect to the cross line's branch icon, and gives the actual crossing a larger space for other overlays.
2) Something, ¿{{UK-railway-routemap? brings a link to a catalog of icons in rail maps. The catalog was huge so Sameboat cut it down with links at the foot of the page to most icons that he hived off into four "type" lists. It might be easier to use if, instead of just one link followed by four, there were direct links (brought up by a new UK-railway-routemap template) to several catalogs of icons.
