FCC Mail Room 
As you may know, in the wake of the tragic railroad accident on September 12, 
2008, in Chatsworth, California that resulted in the death of 25 people, Congress 
enacted the Rail Safety Improvement Act of 2008. This law mandates the 
installation of Positive Train Control (PTC) for commuter and freight rail systems. 
This is an essential, life-saving technology necessary to enhance the safety of our 
nation's railroads, and I remain a strong supporter of rapid implementation of this 
technology. 
The Southern California Regional Rail Authority (Metro link) is on track to 
be the first commuter railroad in the nation to implement PTC on its entire 512-
mile system. They initially sought FCC approval for the acquisition of spectrum to 
implement PTC in March, 2010. I recognize that there have been several 
complications in this matter, including the bankruptcy of the company from which 
they contracted to purchase the spectrum. However, all filings have been 
completed, and the matter has been ripe for a decision by the FCC for more than a 
year, since June of2013. 
I respectfully request that the Commission move as expeditiously as possible 
to conclude its consideration of this application, so that Metrolink can have a 
permanent solution to its PTC spectrum needs, one way or the other. I understand 
that two distinct approvals for license transfers are needed from the FCC, from the 
bankrupt company to its creditors, and then from the creditors to Metro link. If at 
all possible, I would urge you to make these decisions at the same time, to resolve 
this long-delayed matter as quickly as possible. 
Please note that I am not addressing the merits of the issues raised relative to 
Metrolink's applications. I fully expect the Commission to dispose of those issues 
consistent with its statutory authority and applicable administrative and judicial 
precedent. But I encourage the Commission to take prompt steps to act on the 
Metro link applications and related waiver requests, as this is an important matter of 
public safety. 
Thank you very much for your attention to this matter. Should you have any 
questions or wish to discuss this matter, please do not hesitate to call me, or have a 
member of your staff call my Chief Counsel, Neil Quinter, at 202-224-4933.
