Un appareil d'une manœvre simple et rapide permettait au mécanicien de faire à volonté supporter le poids de la machine soit par les roues directrices, soit par les roues motrices et de réduire ou de développer ansi, suivant les besoins, l'adhérence dans une proportion correspondant à la différance qui existe entre la traction sur voie ferrée et la traction sur route ordinaire.
- ALT1: ... that in 1873 the Larmanjat guided rail system was successfully demonstrated at Buckhurst Hill, England, but the system failed completely when used commercially in Lisbon? Source: The Times 31 December 1872 page 4: A section of line on the proposed system had been laid down at Buckhurst Hill and an engine and rolling stock worked over it in the most satisfactory manner. But:[1] page 575: Law report from Court of Chancery, London, that the company formed for the Lisbon tramways had completely failed in its undertaking.
- ALT2: ... that on the locomotives using the Larmanjat guided rail system the driving wheels were loose on the axle and the tractive force was transferred through wound-up springs? Source: [2] Engineering (magazine) 20 May 1870 page 354: "The driving wheels are not connected rigidly to the axle but are connected with it by spiral springs."

Image eligibility:
- Freely licensed:
- Used in article:
- no, but it is merely a crop from a larger version used in the article, which actually works better at the small size to illustrate the hook. So acceptable to me. - Clear at 100px:
| QPQ: Done. |
Overall: 
Thanks for your work on this good article. The picture is a bit fuzzy at the small size but doable; but if this hook will not be used on the first line, then ALT1 also checks out and is acceptable. -- P 1 9 9 ✉ 19:55, 28 May 2024 (UTC)

- @AntientNestor, P199, and PrimalMustelid: Article attributes the claim, the hook doesn't. This should be changed.--Launchballer 14:33, 1 June 2024 (UTC)
