NEW MEXICO (KRQE) – As ridership continues to rise for the state's large commuter rail, concerns are being raised about the number of passengers it carries to offset CO2 emissions. The Rail Runner transports thousands of riders throughout the day, but a recent newsletter from the Legislative Finance Committee said ridership needs to go up if the train wants to offset its carbon footprint. The newsletter states ridership must increase by 23% to reduce emission levels to match that of riders just deciding to take their cars. It also said the Rail Runner sees around 1,900 round trip riders on weekdays with 12,00 tons of CO2 emitted. Old tunes live longer thanks to Albuquerque music-centered group The Rio Metro Regional Transit District, which operates the Rail Runner, said they have seen an increase in riders since the pandemic. Rio Metro said the growth, if continues, will help offset the footprint. They also credit new train schedules for helping with rider numbers. However, they want to purchase more energy-efficient locomotives eventually. The Rio Metro said they hope to offer more connections from the Rail Runner in places like Santa Fe so there are more ways for locals to utilize it. The LFC will hear from the Rio Metro Council about the Rail Runner on Wednesday morning.
