NO, that will be the nr 50, it has both ord (red) and AC=orange, botg go same ways in hte PEAKS they also have expressway workings, YELLOW shield, that do not pass there.
anyway, this thread now has nothing to do anymore with the original: subway feeders.
in THAI BOOkshops and some farang (try asiabooks) are very well produced busguidebooks/maps for sell at 50 bht: thay were quite recently newly published, bu bangkokguide. The map is quite good now in both showing english and that: for thos out of the way places
However: for INNERCITY use its about useless: then use the much more detailed tourist-aimed maps for sell at also 40/50 baht. these are limited to old trusted routes and only show the ''tourist zone'' and moit all of the routes above 120 or so: new since the last 12 years
