Data from [], the web site of the Spanish National Railway. visited 21 April 2003. Works number3 were 1427-1428 in 1871.
Tiny yard engines with outside valve gear and cylinders intended for industrial use. Although Schneider produced 24 50bis four-coupled tanks, only three ran on the Spanish broad gauge. Besides the pair shown, an 1877 engine (works number 1891) went to Assereto & Simon
Jerez Urban was later absorbed by the Andaluces, which owned the locomotive when it was taken into RENFE.
