Your wiring is sound.
The basic power supply should be enough for four loco's.
If you get a booster, get the DB5 Smart Booster Part #

Subject: [w4dccqa] Small N Scale DCC Layout
Hello all new to the forum –
After years of being out of the hobby and never having used DCC, my son and I decided to build a small N scale set. With a foot print of only roughly 3’ x 4’ we are planning to have 4-5 separate tracks and loco’s running. I wanted to set it up for DCC control but am having a little difficulty finding an answer to my main question, which is, can we power the entire layout from one NCE Power Cab? According to information I found on NCE’s website, I should be able to control up to 8 loco’s so I think we are good, my real question is on the wiring to make this happen. Each track will be no more than 12’ in total length, so my thought is to run my main bus wire of probably 16 or 18 gauge and then run two feeders to each track at opposite ends off the bus using 22 gauge. There will only be one turn out off one track with return to same track. With such limited space we are keeping it somewhat simple in that respect. Any suggestions or am I totally off base with what I am planning? Do I need more than the 2 amps the power cab supplies because of number of separate tracks or overall rail length? Should I break the layout into blocks and have circuit protection off the main bus for each track?
