Sticky switch points have a variety of remedies 1. Check for flash, crud, carpet fuzz, dirt and whatever in the turnout making it stick. With the switch motor removed or disconnected, the points should move very freely. Sometimes the rivets that retain the points are clinched too tight. 2. As you have noticed, twin coil machines draw a lot of juice. Make sure they are getting enough. I wire my turnouts with at least #18 wire. The #22 or #24 used by the phone company is too small. Also, the inductive kickback from a twin coil machine makes the push button switches arc, which cruds up the contacts after a while. A major bennie of capacitor discharge turnout power packs is reduction of arcing in the push button switches. Few to no power packs have enough omph to flip two twin coil turnouts simultaniously. Some lesser HO power packs have difficulty powering locomotives and switch machines at the same time. 3. If the turnout is on the rug, or slightly bent, the crossbar can drag on the rug and slow the machine down. 4. Twincoil machines work fine on AC. If you can find a beefy 12 or 12.6 volt transformer, you can mount it in a box and you have a turnout power supply. As long as you make sure the hot connections to the AC line are properly covered (like inside the box) to prevent touching them by accident, and you have some strain relief on the power cord, you are good to go.
