Family lives off I25 in Douglass county and works in parts of Denver. We travel to and from DEN on Amtrak; always nice people, great service. The AAR frequencies are active, negotiating with BNSF dispatchers to get our train through the yards. When comes to the non-RR data, the terminology in the CO Wiki database confuses me. I see CSP vehicles on I25, Denver Police cars and Douglass County Sheriff vehicles on local streets. The cars all seem to have multiple antennas for different bands or services. In the Wiki database I don't see local "police" entries (except for CSP) . What am I missing within the county and municipal organization listings? I am trying to put a collection together for the PRO-106 using the WIN500 software. TIA.
