Editing 2-8-4 (section)

====Tender locomotives====
The CSD ordered three Class 486.1 1’D2’-h3 (2–8–4) locomotives, based on the three-cylinder Class 114 locomotive of the [[Austrian Federal Railways]] (BBÖ). This hand-fired locomotive had a [[Krauss-Helmholtz bogie|Krauss-Helmholtz]] leading truck and the diameter of its coupled wheels was {{convert|1830|mm|in|0|abbr=off}}. Its total weight in working order was 107.6 tons, of which 63.9 tons were adhesive weight. All three cylinders were of {{convert|550|mm|in|2|abbr=off}} bore with a {{convert|680|mm|in|2|abbr=off}} stroke. The heating surface of the boiler was {{convert|253.2|m2|ft2|2|abbr=off}}, of which {{convert|105.6|m2|ft2|2|abbr=off}} were superheating area. The grate area was {{convert|5|m2|ft2|2|abbr=off}} and the locomotive was designed for possible coal dust firing. They had Class 926.0 tenders, which were rebuilt from Class 623.0 tenders.

They were not as successful as expected. One of the Class was tested against a Class 486.0 2’D1’-h3 ([[4-8-2]]) locomotive on the {{convert|248|km|mi|abbr=off}} hilly mainline between [[Žilina]] and [[Košice]] on the former [[Košice]]-[[Bohumín]] Drahy (KBD) line. It proved to be inferior to its opponent in both speed and power.

All three locomotives were allocated to the [[Brno]] shed for most of their active service lives. During the years from 1938 to 1945, they were rostered as BMB-CMD locomotive stock. They were withdrawn from service in 1967 and 1968 and were later used as mobile boilers.
