LCRU
Using the Lionel Trainmaster allows a collector operator to enjoy the advantages of new technology and still keep compatibility with the older legacy systems. A TMCC converted engine can still run on a conventional non TMCC layout as it would before the conversion. This is not possible with a DCC system |
Modification for DC Motor operation
The Lionel LCRU (LiontechControlReceiverUnit) was designed to use AC motors, but by adding a rectifier as shown in the drawing, you can use it to power DC can motors and have full functionality. |
Explanation of the Modification for Two Rail operation
Note there is a 100 micro Henry choke in the return power lead. This choke is necessary when using two rail track to ensure that the signal is not degraded when the engine is turned around on the track .(Lionel track uses the signal on both outside rails) With a two rail system when you turn an engine on the track it effectively shorts out the RF signal to the LCRU in the engine. This is why you put the RF choke in the common lead. The RF choke looks like an open circuit to the RF and it is not shorted out. Leaving it out, the engine will run fine one direction but lousy if turned around. The Headlights are wired for directional control. |
