I agree with @R32 3838 and @T to Dyre Avenue here.
The 46's have been running for about 47 years at this point so replacing them should be a priority. If my math is correct, The 1st Option order should replace about half of the existing fleet of 46's. Then the 1st Option Order alone will replace the rest of the 46 fleet in addition of adding a few extra trains into they system. In what world should that NOT be a priority? Granted, given the current schedule of the order in addition to employee's leaving the Kawasaki plant in Nebreska, I don't expect to see the completion of the first Option order until 2027-2029. It'd be a miracle if we even get the 2nd Option Order (which arguably, I don't think we need the 2nd Option Order unless some 68's decide to shit the bed early)
Better to future-proof the system if thats the case then, therefore adding a level of necessity to these projects.
