Thomas en orden cronológico

Perley's grandson, William E. Price Jr. is credited with coming up with the "Chick Bus" concept after observing a local chicken breeder who was using an old Thomas bus to transport cages of baby chicks from the hatchery to a grow-out farm. Price ran the project by the firm engineers, who after consulting with local breeders and processors, came up with a the Thomas-built "Chick Bus". The purpose-built vehicle included windows that opened from the outside, a ventilated floor and side walls and a heating/cooling system that kept the chicks at a constant temperature, year 'round.
