Overview of the ACEC SNCB 25.5

Discover the SNCB 25.5, a robust and reliable electric locomotive built by BN and ACEC between 1960 and 1961 for the Belgian National Railway Company (SNCB/NMBS).

These locomotives, designed for heavy-duty service, underwent a significant refurbishment between 1973 and 1974, enhancing their operational capabilities.

With a top speed of 130 km/h and a weight of 85 tons, the SNCB 25.5 is well-suited for both freight and passenger transport.

Its Bo'Bo' wheel arrangement and dual-voltage electric systems (1.5 kV DC and 3 kV DC) highlight its versatility.

Measuring 18 meters in length and operating on a standard 1435 mm gauge, the SNCB 25.5 represents a classic era of railway engineering and continues to be a symbol of Belgian rail heritage.
