John, Opposite effect. 2 resistors in series reduces current flow. These are the same 16ohm resistors used in the PS-2 engines. The PS-1 has them wired in series so each drops half the voltage of the track.
The PS-2 are in parallel and effectively 8 ohms, so the current draw is not the issue.
When the transistor conducts at high track voltage and shorts one resistor, the other then gets full voltage and increased current with an effective 16 ohm load. Just an interesting way to approach solving a problem. G
