Hello All,
Well, it depends...
...It depends on how much power (Amperage) each loco and/or consist draws.
I too have an NCE Power Pro DCC system with 5 Amps.
The 5 Amps is divided into five (5) power districts with one district being a wye with an auto reverser.
Each district is protected by an NCE EB1 and the wye by an AR 10.
I also installed a DCC Concepts Alpha Meter which monitors both Amperage and track Voltage in real-time.
This allows me to measure the Amperage draw of individual locos as well as consists, along with track voltage.
As an example:
If the four (4) locomotives on your current pike draw a total of 2-amps (0.5 Amps each) and you add four (4) more- -older motored locos- -that draw one (1) Amp each, that's a total of six (6) Amps total, which will exceed the Amperage of your single booster.
If each loco draws 0.5 Amps, eight (8) locos only draw four (4) Amps total. Plenty of power for a 5 Amp booster.
Don't forget to factor in any other rolling stock or DCC-driven accessories that draw power from the booster.
Hope this helps.
