Lots of power. Older style. I believe 110 Watts. Has Locomotive whistle and direction control. No Loco bell control for newer locomotives. No indicator lights for power on or derail indication. You'll need a track power lock-on with power light for indications. Replacement handles readily available (the direction & whistle handle will break) and you might want to replace the power cord if it's real old. Simple, screwdriver and solder iron.
