The first Meyer locomotive, ''L'Avenir'', was built in 1861 and was also derived from a Semmering Trials design, the {{interlanguage link|Neustadt (locomotive){{!}}''Neustadt''|de|SStB – Neustadt}}. This had a similar arrangement of two power bogies to ''Seraing'', but a conventional single boiler. Meyer used compounding at first and so the cylinders were placed at the inner end of the bogies, where the intermediate pressure pipework between them could be kept shorter.

The most numerous Meyer locomotives were a German {{TrackGauge|750mm}} narrow gauge class, the [[Saxon IV K|DRG Class 99.51–60]], of which 96 were built.

The need to place the boiler above the bogies limited the depth of the [[firebox (steam locomotive)|firebox]]. [[W. G. Bagnall]] worked around this by using [[Bagnall boiler|their own boiler design]] with an internal firebox within the circular shell.
