Analog or digital control – what to choose?

Digital control systems allow multiple locomotives to run independently on the same track, while also offering access to sound and lighting features. This is a significant advantage over traditional analog operation.

About the SM31 locomotive:

The SM31 is a heavy Co’Co’-type diesel shunting locomotive developed in the 1970s by the H. Cegielski factory in Poznań. It was designed for heavy shunting operations in large freight yards and for use on steeply graded lines requiring high traction.

With an output of 880 kW and a weight exceeding 115 tons, the SM31 could move very heavy consists with ease. It features a compact design, central driver's cab, and reinforced construction. During Era V, these locomotives were widely used across Poland, especially in the industrial and port regions of Silesia.

This PIKO model faithfully captures the proportions and livery of this powerful workhorse, making it a valuable piece for any Polish model railway collection.
