The Train Experimenter Shield (TES) for the Arduino Uno (and most clones) is a receiver/decoder for the Lionel Legacy and compatible Systems. It receives its power from the AC voltage present on the Lionel three rail track (18VAC, nominal). See the TES User Manual for more detailed information.
Due to the complexity of the TES, it is only offered as a fully assembled and tested Shield. However, the fully assembled and tested TES can be purchased with several options and discounts.
This "PDI to PDI" splice pretends to be a very short Lionel PDI cable and allows you to daisy chain two Lionel PDI cables together while respecting the voltages and communications on the devices.
TAS (Train Actuator Shield) Max version
This model of the TAS has a built in "Snubber circuit" to improve the reliability when controlling somewhat inductive loads (like vintage Lionel animated accessories). It handles four command paths - signals on Arduino Uno digital pins 4, 5, 6, and 7 (Match Commands 1, 2, 3, & 4). No assembled version is available. You can get either the raw PCB or the complete kit.
This is a TES Command Cube Bundle
It consists of a Train Experimenter Shield and a custom enclosure. One Train Actuator Shield of your preferred type must be selected. You will also need an Arduino Uno. A clone is offered for purchase separately.
