I have been looking for an alternative to purchasing terminal strips to wire up my layout. I came across

They sell a terminal connector (part number CMB4) that you can connect together and make strips as long as you like or you can purchase pre-made strips in any length. Add the internal jumper and you have a terminal block that you can connect all your hot wires too. In this configuration that one feeder from the source and 19 to the tracks. The block is about 1” X 1” X 3”. Cost was less than $9.00 each.
