So...first they pull the plug on routes 54 and 55; they replace the 54 with the 77A past Walkinstown and then they basically re-route the 55 via the old 54 routing, taking it off Cashel Road and Crumlin Centre and re-numbering it as the 155 in the process. But that's not good enough for DB, because they have this 19A that's currently terminating at Kelly's Corner. So, away with the 155 and down goes the 19A to Limekiln Farm in Greenhills. A bus route that goes all the way from Glasnevin North to Greenhills...
Even worse, the route 19 still goes to Bulfin Road on the border of Kilmainham and Inchicore, or that's where I presume Bulfin Road is. (Come to think of it, the Ordnance Survey map never delineated the traditional borders of the districts; anyone have a map showing them?)
How about this, then: Re-route the 19 down via Harold's Cross and into Kimmage the same way the 19A goes; but then, have the 19 run via Whitehall Road East to terminate at Limekiln in Greenhills, then re-route the 15A via the current 54A routing (Fortfield Road, Fortfield Park, Templeville Road), but from there, I don't know whether to keep it going to Limekiln itself or send it to Templeogue via Cypress Hill Road to join most of its other route 15 brethren? who cares, it gets rid of that redundant 54A route...man, I must be thinking like a DB route planner now?
Oh, almost forgot, send the 20B back to Bulfin Road and re-number it as the 20 once again.
