The states of New Mexico and Colorado agree to the consideration of the enactment of such laws or constitutional amendments exempting the said railroad or its operations from various laws of both states as both states shall hereafter mutually find necessary and proper.
Nothing contained herein shall be construed so as to limit, abridge or affect the jurisdiction or authority, if any, of the interstate commerce commission over the said railroad, or the applicability, if any, of the tax laws of the United States to the said railroad or its operations.
