when the legislators agreed to continue to fund the project, they inherently gave approval that it should be completed as planned.  they were not asked whether the rail project should be altered in any way nor did they feel that it was their duty to decide what changes to the project should be made.  it is a city project, not a state project.  by using the tat they intervened in the project so they could monitor the costs and performance of the city and hart..  if they only agreed to extend the surcharge, they could not insert the control provisions in SB4.  they did it purposefully so they could monitor the project financially and oversee the construction process.  that is why Caldwell wanted only the surcharge extension as he did not want the state to poke their nose into the project and tell them what to do.  but maybe it is good that things transpired this way,
