This is the new (2013-on) Sport Power Base that replaces C8217. It comes with two 60-ohm Sport hand controllers. Powerbase and controllers are wired for dynamic brakes. One P9403 1.2 amp power supply plugs into this power base. A Sport to Classic converter track section is included, making this power base compatible with either Sport or Classic track. Power Base + converter track = one full straight. Length in inches - 13-3/4"
Contents: 1x Powerbase, 1x Half Straight, 2x Hand Controllers
Note: If you want separate power to each lane you can't have it with this power base. For separate power per lane you need the older C8217 or C8241. The C8241 can be used with either 2-lane or multilane tracks and requires the P9203 power supply with round plug (1 per lane needed for separate power).
