Sadly, not all other routes use R143 because of missing characters on the displays...
The , , and ran them, some were signed as Shuttle... but they've rarely been on the since the used R160s and R179s often, and back then it used R110B, but I don't think I was able to upload the R110B Side and/or overhead for it, so the R110B displays are not available unless I upload those first.
