I just saw a report about MTA station with MRN#. Can someone tell me what MRN stands for? Thanks.

MRN stands for “Master Reference Number”, and is a unique identifier for each station in the system.  You will find these in the “Station ID” column of our Stations.csv dataset (also linked from our static datasets page here).  Station complexes are also assigned MRNs, and these can be found in the “Complex ID” column of the same file.  Station complex names, in turn, are available in our StationComplexes.csv dataset.
