I suppose it's interesting that the coach (59? JCZ 5225 ex OXI 52? ex 2nd-hand from England in late 1980s) that 458 replaced was originally owned by NIR and based in Craigavon for Belfast - Dundalk rail replacement services. The passenger comfort standards on rail replacement buses were very high then.
It would be ironic (showing how standards have dropped since NIR / Ulsterbus-Citybus management merger) if the coach went back there now near the end of its life but I think it went to the driving school?
