Lambert have had a few cancelled mostly St Mungos HS ,Graeme High and another few .At Balfron? That has been the only school where it has been suggested that Carrs were taking over.
As far as I can tell First operate the following from the High School:
308, 313: Not council contracts
507, 510, 512, 513, 515, 516, B10 & B12: All listed as school buses on the council website.
Of the above the 308, 510, 512, 515 & 516 have been cancelled, the rest remain registered at this time. An increase of four for Carrs directly correlates with the four 5xx services cancelled by First.
