I'm sure the question has come up on TO before, but my searches didn't turn up anything. I am in the market for a new scanner for my Amtrak trip back East in April. It has been many years since I have used one, so I'm sure the technology has passed me buy; obviously, or I wouldn't be asking other members for their advice! I looked at the Bearcat 72 and 92 on line, but I didn't see that there was a lockout device to keep from accidently changing channels.
I would appreciate any thoughts or recommendations you all have on a good scanner to buy. Barry Stone. First, to answer your subject line: You don't need a trunking scanner to listen to railroad communication.
Trunking is used mostly by public service groups, like police, fire, and transit, but can also be used around airports for ground operations, and by bus and taxi companies. Even then trunking is only used in larger cities. Thus, if you want to use the scanner for listening to other than railroads, consider a trunking scanner.
Otherwise, you don't need it, nor do you need a digital radio, for that matter. However, they can be difficult to program, don't have some convenience features that are found on scanners, which can be useful, or those features can be difficult to use. They have been around since and may now be purchased from a variety of vendors or purchased in used condition through services such as eBay.
The Motorola APCO Project 25 system is the only digital system that may be heard on radio scanners, and currently only on a few high-end models see below for more information on digital radio.
Make sure the scanner model you buy can track the type of trunked radio system used in your area. The tables of scanner models in Categories 4 and 5 contain this information for each scanner model. If you are only monitoring analog systems, a Category 4 radio will be sufficient and will be significantly less expensive than a Category 5 radio. If any of the police, fire, or other services you would like to hear in your area use the digital APCO format, regardless of whether the system is in conventional or trunked mode, you will need a police scanner in Category 5.
Please note that all Category 5 scanners can also monitor analog conventional and trunked systems. If some departments in your area use analog systems and others use digital, a Category 5 scanner will be able to monitor both. Terms of Service Linking Policy. Part 2: Technical Tidbits.

There are several types of trunking systems but they all work in much the same way. There are differences in the way they get programmed into scanners as well. For scanner listeners these trunked systems add a layer of complexity to the programming.
Depending on the type of scanner and the type of trunked system the method used to program differs. Motorola and APCO25 systems do not need the frequencies in any particular order.
HomePatrol and other scanners with the Database feature will have these Trunked System parameters already programmed so you can just select the Service and location to listen to them.
