T4XA

Decoder
SKU: 1346
    Description

    The T4XA is a 4-function, multi-purpose HO-scale decoder. The T4XA may be used in locomotives which have ditch lights in addition to forward and reverse headlights.

    IMPORTANT NOTE: The T4A decoder is identical to the T4 decoder, but does not include a harness! The T4A can be plugged directly into a locomotive's 9-pin connector. If your locomotive is equipped with an 8-pin NMRA plug, you should consider the DP2X, or use the T4A with an adapter harness which can be found under our Harnesses section. 

    Note: As of August of 2022, All T4 decoders new come equipped with a plug/jack for a Keep Alive® with the corresponding connector.
