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:

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?

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.

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)
