Multiple press-button (or momentary centre-off toggle) switches can be simply parallel connected, and are only switching 12V low-current logic lines. Personally, I'd opt to deploy a stall-motor 555-based circuit a la the Rob Paisley "Electronics for model RRs" website. It's concievable that this could present a short circuit condition, with possible bad results. However, I forsee a potential issue is 2 or more operators all try to throw the same turnout (and thus are holding down their respective momentary toggles) at the same time. The power supply is not being loaded down by Tortoises "at stall". Using such centre-off/momentary toggles has the benefit of only powering any given Tortoise when it's in-motion. However, if the user presses and holds the toggle, the Tortoise will make the desired movement. With "centre off" toggles, just "flicking" the toggle won't completely throw the Tortoise, you're absolutely on the ball there. However, once at the desired position, power can be removed and they will stay essentially where they were left. In basic terms, yes, Tortoises need constant power while changing position.
