Union Station Railroad Frequencies Update

Spent some time at Union Station on Saturday, and was able to update the rail frequencies in use. Here's the latest list:

160.2900 [114.8] Yardmaster (input 161.3700)
160.3500 [114.8] Train Maintenance (input 161.1450)
160.4400 [114.8] Station Services (input 161.4450)
160.9200 [ CSQ] Amtrak - Northeast Corridor Road (also uses [146.2])
160.9950 [ d023] Amtrak - Engineering (R)
161.2050 [146.2] Amtrak Police - Car-to-Car
161.2950 [192.8] Amtrak Police - Dispatch (input 160.6650)

The four input frequencies were previously unknown. CSQ seems to be used more on 160.9200 than the listed tone. I was unable to find an input for 160.9950.
