Is your LGB® Locomotive ready for DCC (MTS)?


The marking (1) and stickers (2-5) displayed below are usually found of the bottom of LGB® locomotives that were manufactured before 2006; they are used to indicate the DCC (MTS) status of a locomotive.

Locomotives manufactured after 2006 do not usually bear stickers indicating their DCC (MTS) status; the information may be available in the user's manual or on LGB's website.

LGB DCC MTS Logos

An LGB® locomotive with an engraved "D" on the bottom side of the gearbox is suitable for DCC (MTS); the "D" marking indicates that the gearbox is a 4-pin gearbox with a motor that is electrically isolated from the track. A gearbox Without the "D" marking may have to be converted to a 4-lead gearbox to become suitable for DCC (MTS).

An LGB® locomotive without one of the 4 stickers "2-5" is either manufactured after 2006, or missing its sticker, or pre-DCC (MTS). The locomotive may require disassembly to determine its DCC(MTS) status; pre-DCC locomotives should have their basic electronics removed for conversion to DCC.

Sticker "2" indicates that an LGB® locomotive is DCC ready and equipped with a 6-pole decoder interface. An interface cable (Massoth 6-pin Interface cable, item # 8312061) is required to connect a decoder to the locomotive's PCB board. The 6-pin decoder interface is plug-and-play compatible with the LGB® 55021 decoder, the Massoth eMOTION L decoder, the Massoth eMOTION XL decoder, and the Massoth eMOTION XLS sound decoder.

Sticker "3" indicates that an LGB® locomotive is DCC ready and equipped with a 10-pin direct decoder interface plug-and-play compatible with the LGB® 55021 decoder, the Massoth eMOTION L decoder, the Massoth eMOTION XL decoder, and the Massoth eMOTION XLS sound decoder.

Sticker "4" indicates that an LGB® locomotive is DCC ready and equipped with an onboard-decoder that is suitable for both digital and analog operation. The Massoth S sound module is perfectly suitable for adding sound to LGB® locomotives equipped with an onboard-decoder.

Sticker "5" indicates that an LGB® locomotive is DCC ready and equipped with the new 10-pin DCC interface plug-and-play compatible with the LGB® 55027 MTSIII decoder, the Massoth eMOTION XL decoder, and the Massoth eMOTION XLS sound decoder.

In 2014 LGB introduced a new 28-pin decoder interface which they represented in their literature by symbol "6". The interface, sometimes referred to as the LGB/Märklin Gauge 1 interface, is plug-and-play compatible with the LGB® 55028 decoder, the Massoth eMOTION XL-M1 decoder, and the Massoth eMOTION XLS-M1 sound decoder.
