Class 143/120-2071 (Locobase 3334)

Data from [], the web site of the Spanish National Railway. Works numbers were 995-1000 in 1879.

Of the six Cockerill-built six-wheelers that went into service in 1879, two of them--144 and 148--were taken into the RENFE in 1941.

Class 151/120-2101 (Locobase 3336)

Data from [], the web site of the Spanish National Railway. See also Pere Comas, Breve Historia de la Traccion Vapor en MZA, Trensim TS10H002, Julio de 2011, pp. 30-31. Works numbers were 3388-3391 in 1887; 3415-3418 , 3506-3509 in 1888, 3637-3640 in 1889.

After decades on the Madrid-Atocha run, where the "catalanas" acquitted themselves very well through the Madrid-Alicante-Zaragoza and RENFE eras, all were scrapped before 1961. Comas comments that "lamentably, none was conserved by the Museo del Ferrocarril in recoginition of its historic value."

Class 23/120-0201 (Locobase 3328)

Data from [], the web site of the Spanish National Railway. See also Pere Comas, Breve Historia de la Traccion Vapor en MZA, Trensim TS10H002, Julio de 2011, pp. 30-31.

The Spanish National Railway Museum website, [] (accessed 22 Feb 2007), says that this class originally came with a separate tender. It was delivered between 1877 and 1882 to pull high-speed trains for the TBF. When the MZA took over the TBF, it converted the class into tank engines for local service in Catalonia.

Class 3/120-2031 (Locobase 3331)

Data from [] and [], last accessed 13 July 2004. Cail produced works numbers 1274-1275 (subcontracted to Parent-Shaken) and 1238-1243 in 1864 (road numbers 3-10), Haine St Pierre's works numbers were 48-50 (road 11-12, 14) in 1864, Couillet works 133 (road 13), Saint LTonard works 210-214 (road 15-19), and lastly Coulliet works 134-135 (road 21-24).

When delivered to the Ciudad Real a Badajoz, each member of the class was named for famous explorers, conquistadores, Roman emperors, and political figures from the Nineteenth Century: Octavio Augusto, Santa Catalina, San Fernando, Santa Teresa, Pe'arroya, Virgen de BelTn (all from Schaken/Cail); Viriato, Trajano (Haine St Pierre); Pizarro (Couillet); Vasco N+'ez de Balboa (Haine St Pierre); Garcfa de Paredes , Mu'oz Torrero, Calatrava, Donoso CortTs, Campomanes (St Leonard), Quintana (St Leonard or Coulliet.

All were absorbed by the Madrid, Alicante y Zaragoza when that railway absorbed the CRB in 1880. Sixty years later, three remained to receive RENFE numbers: Pe'arroya, Calatrava, and Quintana.

Class 60/149/120-2121 (Locobase 5967)

Data from []

, the web site of the Spanish National Railway (19 Mar 2004). See also Pere Comas, Breve Historia de la Traccion Vapor en MZA, Trensim TS10H002, Julio de 2011, pp. 30-31. Works numbers were 9-10 in 1895.

Three sets of MZA 2-4-0s from this period are shown in Locobase (see 3336 and 3328 for the others)-- together their engine numbers ran from 143-166. 2-4-0 arrangements were rapidly phasing out because of the need for better tracking, but this pair was ordered after the first set proved well-suited to the service they were on. Their works numbers show just how new to

the business was the MTM.

Like the others, the two operated on the Madrid-Atocha service where they were known as "las catalanas" (The Catalans). Both were scrapped sometime before 1961.

Decades later, when the MZA's rolling stock was nationalized by RENFE in 1941, the two received their final numbers.

Class 65/120-2011 (Locobase 3330)

Data from MATERIAL MOTOR RENFE 1947 diagram book posted by carlos lavagoneta arroba and retrieved from Picasa [], last accessed 1 June 2014. See also Pere Comas, Breve Historia de la Traccion Vapor en MZA, Trensim TS10H002, Julio de 2011,p.10-11. Schneider-Creusot delivered the first 26 producing works numbers were 410-419 in 1859, 641-650 in 1863, 663-668 in 1863. Evrard's works numbers were 18-36 in 1862; 41, 43-47, 51-55 in 1863. Gouin completed the class with road numbers 120-128 in 1864.

MZA procured these as express engines according to [] (accessed 7 September 2005), which adds that one still served RENFE 100 years later as a switcher.

They were known as "Creusot viajeros" (passenger Creusots) and came on the road from 1862 to 1864. Until the MZA acquired the compound express engines in 1901, this class was the principal power for the best trains such as the Express 49 (uptrain from Madrid to Zaragoza) and 50 (mirror train from Zaragoza to Madrid).

Many of the class then migrated tothe Valladolid a Ariza service.

Only seven survived to taken in the RENFE as their 120-2011 class. Ex-MZA 108 went to the Cementos Portland as their CP 2 and, when retired, was preserved at the Olzagutia factory in Navarra.
