feat(editor): the lines out of a station take the automatic block of 3 or 4 aspects, the block sections no shorter than the braking distance or than half of it, the block signals placed with the templates of the aspects and those standing swapped for them; block boundaries drawn by hand, a click on a track of a line of the automatic block placing block signals across both tracks there, numbered after the hectometre, the tracks cut beyond them and the block sections named and switched anew, a click on one standing taking its signals and the switching of their sections away, a step of undo each, the lengths of the sections either side shown at the mouse. A line whose block signals stand keeps them as they stand, Set the line signals placing them evenly only on a line without any, and one whose block signals no block section of the editor switches keeps the block of the scenery untouched; the signals of the other block left along a line taken away, but where it shares its track with a line of that block, and the switching of the sections gone from the lines set with them. A block signal of 4 aspects is checked for a section no shorter than half the braking distance, and fitted with templates of its aspects only
