It’s been a long time coming but new ‘ecological’ buses are gradually being introduced onto Guadalajara’s streets. State authorities hope it won’t be long before they become the norm rather than the exception. The buses, which are running on various routes, including 51A and 51B, 371, 633 and 368, each cost 1.2 million pesos (91,000 dollars). Currently, 290 of the green-painted buses are in operation, 50 of them powered by natural gas. Owners and drivers, however, are pushing for fare increases on routes using the new buses.
