One of the most common questions we receive is "Which DCC System Should I Purchase?"
To answer this question, we need some information - what scale is being operated and how many locos are expected to be run simultaneously. This information is needed to size the system. Notice, that the size of the layout was not the first thing we need to know. Contrary to popular belief, more track doesn't by itself equate to the need for more power.
For N and HO Scale layouts, there are many options. To narrow down the solutions, the number of locos comes in to play as the sum of powered devices determines the power requirements of the system, which is measured in Amps (A). As a rule of thumb, we assume about 1/2A per HO Scale loco and 1/3A per N Scale loco. On larger layouts, other items may need to be included such as DCC controlled switch machines and lighted cars.
Popular DCC Systems for N and HO Scales
NCE Power Cab
The 2A system can operate 5-6 N Scale locos or 3-4 HO Scale locos. This system includes the power supply. It can be easily upgraded to a 5A system with the purchase of NCE's Smart Booster.
MRC Prodigy Express
The 1.6A system can operate 4-5 N Scale locos or 2-3 HO Scale locos. This system also includes everything you need to get started. Can be upgraded via one of MRC's separately purchased boosters.
MRC Prodigy Advanced
This 3.5A system can handle up to 10 N Scale locos or 5-7 HO Scale locos. This system comes with the power supply. Can be upgraded via one of MRC's separately purchased boosters.
NCE PH-Pro 5A
The 5A system can power up to 15 N Scale locos or 10 HO Scale locos. For larger layouts, it can be expanded by purchasing additional NCE boosters. Like the smaller NCE Power Cab, it can be used with additional NCE throttles. This system is one that is very commonly used by model railroad clubs.
Bachmann EZ Command Plus
This is an extremely basic system designed to let you operate DCC equipped locos. It does not allow for any loco programming. Bachmann does offer a 5A booster which will allow for more locos to run simultaneously, but Bachmann no longer produces throttles for additional users.
Both NCE and MRC also produce Wireless versions of their products (and paths to upgrade), which allow them to work with their respective wireless throttles.
What About G Scale & O Scale?
G scale and O scale layouts typically require a higher voltage, which eliminates some systems from the equation. These layouts also require much more power than their smaller counterparts. Unless the layout only includes a single loco, a larger 10A system along with additional boosters may be required.
In a future blog, we'll discuss layouts that need more power and the options available.
