Oeste / Plasencia _ Astorga 0-6-0 Locomotives in Spain


Class Details by Steve Llanso of Sweat House Media

Class 030-2107 - El Alagon (Locobase 3418)

Data from [link], the web site of the Spanish National Railway. Also The Spanish National Railway Museum website, [link] (accessed 22 Feb 2007).

This domeless engine proved equally capable of hauling passenger trains as well as freight. It first entered service in France on the Oullinis railway, moving to the Medina del Campo a Salamanca in 1871. Through absorptions by Oeste and RENFE, this locomotive carried on and eventually was preserved.


Class 030-2557 (Locobase 5528)

Data from [link], the web site of the Spanish National Railway.(21April 2003).

Almost 30 years after delivery of the immediately previous batch (401-410) to its predecessor MCP, Oeste went to a local constructor for 12 more .The only change was an increase in boiler pressure. A photo shows two big air reservoirs laid horizontally between the stack and the steam dome.

All 12 were absorbed into RENFE in 1941.


Class 030-2569 (Locobase 5517)

Data from [link], the web site of the Spanish National Railway.(21 April 2003). See also [link] . Railtren comments that this pair of engines had a larger boiler than usual and were attempts to replace 0-8-0s that were out of service.


Class 191/030-0201 (Locobase 5960)

Data from [link], the web site of the Spanish National Railway (19 March 2004).

This little saddle tank had straight sides and a very slightly curved top with rounded corners. It endured long enough to be taken into the RENFE when the latter was formed in 1941.


Class 203/030-2540 (Locobase 5516)

Data from [link], the web site of the Spanish National Railway.(21 April 2003).

Of the original 17 locomotives in this class, only two were taken into RENFE when that national railway formed in 1941.


Class 252/030-2502 (Locobase 3452)

Data from [link], the web site of the Spanish National Railway. See also "Serie 252 a 256 (RENFE 030-2502 y 030-2503)", [link], last accessed 18 November 2013. Works numbers were 949- 952 in 1878 and 1373-1375 in 1884.

Four Bourbonnais type 0-6-0s with separate tenders arrived on the Medina del Campo a Zamora y Orense a Vigo (MZOV) in 1878 (works numbers followed by three more in 1886; they were given road numbers 50-53, 55-57. Of these, five were taken into the Oeste as 252-256. Their names were Pontevedra, Mino, Sil, Cabe, Louro. And of the Oeste quintet, only the 252 and 256 were given class IDs by RENFE in 1941, being numbered 030-2502 and 030-2503.

One other locomotive, 51, was converted to an 0-6-2 tank engine in 1911; see Locobase 3425.


Class 301/030-2519 (Locobase 5525)

Data from [link], the web site of the Spanish National Railway.(9 May 2003). Works numbers were 2017-2025 in 1897.

The P a A had 10 of these Belgian-built 6-coupled for freight service between Salamanca and Plasencia. The AP rolled into the Madrid-Caceres-Portugal (MCP), which later merged with the Oeste.

According to Justo Arenillas, writing in Lineas del Tren (reproduced on [link], viewed 28 April 2003) -- as freely translated by Locobase -- "the most peculiar characteristic of this series is that the locomotive's frame was located inside the first two axles [i.e. hidden by the drivers], but on the last axle was located outside. This left more room to be able to locate a wider firebox with more grate area." As a result, Locobase notes, this design's grate area was among the largest of any 0-6-0 put into service anywhere.

Oeste took over the class in 1928 and seven survived to be taken into RENFE when that national railway formed in 1941.


Class 401/030-2527 (Locobase 5527)

Data from [link], the web site of the Spanish National Railway.(21April 2003).

Follow-ons to the Belgian-built batch of a few years earlier, this class had a different tender and slightly different weights.

All ten were soon taken into the Madrid-Caceres-Portugal (MCP), which was absorbed into Oeste in 1928 with the same numbers. RENFE in 1941.
