Manufacturer description
ALPHA MIMIC 12x STEAM Era 3-light Ground Signal – A pack of 12 x 3-lamp weathered-aspect plug and play signals in 4mm scale (OO), complete with control board and accessories.
The DCD-MGS-BR is the classic 3-lamp ground signal. It was first introduced in the mid 1930’s and spread far and wide. Most are still in use today. This makes it a great choice for layouts of many prototypes and periods. The STEAM era version has a slightly yellower “White” aspect, as ground signals in that period were often covered with tar-based “weathering” from steam locomotive induced pollution.

The DCC Concepts Alpha Mimic Pack (part number DCD-MGS-BR) contains twelve 3‑lamp ground signals in 4 mm (OO) scale. Each signal is a weathered‑aspect, plug‑and‑play unit with a yellow‑tinged “white” aspect appropriate to the STEAM era, and the pack includes a control board and the required accessories.
The signal design originates from the mid‑1930s and was widely adopted by the four major British railway companies – LNER, LMS, GWR and SR. It remains in use on many heritage lines, making it suitable for model layouts representing a range of prototypes from that period.
