NOTE (1): The number of locos which may be RUNNING at any given time is limited by the Track Current capability of the boosters supplying the power district where they are operating. The Loco roster is the maximum number of different loco addresses which the command station will remember at one time. When you DISPATCH a loco, you remove it from this memory. When you SELECT a loco, you add it to this memory.
NOTE (2): Jump ports allow a power pack to function as an additional throttle - providing direction and speed information, but not supplying motive power.
NOTE (3): The two amp rating for the PowerCab is a maximum surge current. Continuous operating current will be less - the power supply provided has a continuous rating of 13.5 volts at 1.1 Amps and operates off 115 or 230 volt mains. Can be expanded to use 3 additional throttles and provide 3 amps of track current with the SmartBooster.
NOTE (4): This data is assembled from many sources and is as accurate as I can make it. Please report any inaccuracies. Much of this data is NOT published by the manufacturers and had to come from personal experience. Litchfield Station will not be liable for errors or omissions.
