321 diesel

More powerful than the 313, these machines are ordered in order to complete dieselization in Andalusia and Galicia and if required to begin it on other areas.

Design

The 2100 are machines of the model DLL 500 S (or standard FDP 9) of ALCO. They are equipped with an evolution of engine 251 B whose production stops in 1963 and of a case typically Spanish Bi-cabin, in order to avoid the problems encountered with the machines of the series 316 and 318. A steam boiler Heating Corporation standard Clarkson OK 4616 enables them to tow passenger trains. The initial order relates to 60 units. In front of the good performances obtained, the Renfe decides to dieselize the network completely and for this reason, a last order of 20 units placed in two batches. All the series leaves factory in traditional the delivered green one and yellow of the time.

Service

The first arrived machines of the the United States are unloaded with Sestao, in the port of Bilbao, January 9th and 11th 1965. They are assigned at once to the deposit of Orense.

In 1966, the series is distributed between Seville (21 machines) and Orense (37 machines). In Andalusia, they are used in competition with the 313 and 316 at the head of the goods and passenger trains. After delivery of the totality of the series, they ensure all the services on the center, will extremadura it, the Andalusia and the Galicia. Progress of the electrification and the arrival of the 333.0 are synonimes of decline. They still ensure some services noble travellers with the final section of the Atlantico Expreso between Betanzos and El Ferrol, that of the Iberia Expreso and the express train of Madrid between Bobadilla and Algesiras. With the beginning of the year 1980, they replace more and more ferrobus series 591.3 on the bus services. A test of installation of the electric heating on the 2117 is not crowned success. Moreover, the arrival of the Camellos of the series 592.0 and 593 the hunting of the last bus services. At the end of the years 1980, they are confined with the traction of the goods trains and the heavy operations in great sortings. Some are even used as snow-plows in the collar of Pajares . Part of the series profits from a remotorisation to the beginning of the year 1990. With this occasion, the steam boiler become useless is deposited. From September 1990, some also receive new decoration " taxi". Up to now, the few reforms are the result of accidents (2174 the 12/15/1972, 2143 the 10/25/1978, 2133 and 2137 the 11/14/1983).
