Over the holidays, some may have missed an op-ed piece in the Pioneer Press written by the top local supporters of the Central Corridor light rail line. They admit there will be some vibration impacts on the Minnesota Public Radio headquarters in St. Paul, but said those problems could be mitigated.

Met Council Chair Peter Bell, Ramsey County Regional Rail Authority Chair Jim McDonough and St. Paul Mayor Chris Coleman said in the piece that MPR was well aware that the line was scheduled to run down Cedar Street when it built its new studios there several years ago and that delaying the process for further study -- as MPR has asked -- would cause a delay of at least one year and maybe more.

They urge MPR to "get on board" so as to "not jeopardize its chances of winning federal funding that is essential for construction."

Also last week, MPR's news division reported on a new study that shows light rail vibrations that could affect eight sensitive places along the proposed train route can be resolved via technology. And officials have set aside millions to make it so.
