Former schoolbuses are in regular use and they are very common in Latin America, US and Canadian schools export their old yellow schoolbuses in Latin American countries after one decade. They are an alternative and an economical choice instead of buying a new bus. Sometimes converted to railbuses, but usual not. I think this kind of ex- shcoolbuses are a nice idea for the Tropical Climate of openTTD.
