Madrid-Saragossa & Alicante 1301 to 1308 and 1321 to 1345

In 1913, Hanomag built eight 4-8-0 locomotives for the MZA which had a driver diameter of 1,600 mm and were numbered 1301 to 1308. In contrast to the 1101 series with 1,400 mm drivers that was ordered for steep climbs, the new series was to deliver better performance on less demanding lines at higher speeds. They had a higher boiler pressure and were four-cylinder compounds with a common piston valve for each set of high and low pressure cylinders. The inside cylinders were mounted in a way that they could be accessed from the front for maintenance.

The distance between the third and fourth driving axle had to be increased to make space for the firebox. This resulted in a driving wheelbase of 5,700 mm, but the last axle had 20 mm of lateral play, decreasing the rigid wheelbase to 3,400 mm. They were run up to speeds of 105 or 110 km/h and their power was indicated with 2,050 hp. The requirements included to haul 280 tonnes on inclines of 1.5 percent at 50 km/h, or 340 tonnes on the level at 100 km/h, for that this amount of power was more than sufficient.

They delivered better results than the series 877 to 880 Pacifics which had been built by Maffei and had largely the same boiler. So 25 more were ordered to be built in 1914, this time from ALCO which allegedly had to be persuaded to build a 4-8-0 instead of a Mikado. These locomotives were numbered 1321 to 1345, with a gap to the first batch. From 1927, they were challenged by the series 1701 4-8-2. With the founding of the RENFE, the first batch became 240.4051 to 4058, while the second batch became 240.4061 to 4085. The RENFE mainly used them in freight service and withdrew all between 1964 and 1966.
