Almost 30 years after the founding of the StEG, the influence of French financing was still noticeable, so that the express locomotives were built based on the Paris-Orléans. Thanks to the 2-4-2 wheel arrangement, a larger firebox could be accommodated than with a 4-4-0, but the carrying axles' not yet fully developed centering system resulted in insufficient running smoothness. When the StEG was separated, 26 came to the Austrian part and 32 to the MÁV. The BBÖ retired their locomotives by 1928, after six had come to GySEV. The latter were retired between 1951 and 1959.
