- Doesn't really add much except that it still hasn't reached production. But may as well add it as a reference to the "Not yet mass-produced" clause in the disadvantages section. For many compound steam engine locomotives, the minor improvement in power was also found to be not worth the extra expense and complexity. Stepho talk 00:47, 24 February 2024 (UTC)

[edit]it is possible that my comment reflects mis-equivalences of italian/english terms. But I understand that the 5th stroke occurs DURING the other four ones (with DURING=SIMULTANEOUSLY, not DURING=INSIDE). If so this should be explicitly stated, because 5-stroke should mean 5 consecutive steps. thanks 151.29.62.127 (talk) 08:00, 5 July 2025 (UTC)
- Step number 4 – Initial exhaust/re-expansion is the supplementary step in the system comparatively to the four-stroke model. This step occurs outside of the main cylinders arrangement, the expansion being that of the one supplementary or auxiliary cylinder set on the piston engine crankshaft. --Askedonty (talk) 17:17, 6 August 2025 (UTC)
