Yes I have taken notice to many changes of routes in the Bronx. Honestly I love it now with the 36 bus being confined to East Tremont Avenue now. You get to the heights and back so much faster now!!!
With regard to the Orion 7 next gens, I have already expressed my views about this. The MTA should save some next gens. It is still a very innovative design. It would be a very bad choice to retire all of them. The acceleration and instant torque is still robust. Very fast bus. Very fun to ride on. More exciting to ride than Beeline's Nabi Hybrids.
The MTA should save about 30 next gens. Clean and sanitize them inside real good. Give them new shocks and retune the engines. That's it.
You don't want to scrap all of them. Trust me.
