Brian The Signal Engineer Posted May 26, 2021 Share Posted May 26, 2021 Can anyone tell me why the model rail fraternity use the term FROG for the crossing of a set of points? Every time I read this in an article it makes my skin crawl. I am very happy with the likes of the amphibian creatures and even good old Kermit. 1 2 Link to post Share on other sites More sharing options...

RMweb Gold The Stationmaster Posted May 26, 2021 RMweb Gold Share Posted May 26, 2021 I presume it was picked up by some early model railway writer from the American and the term has, gratingly in my case, stuck. any attempt to change it seems to fall on deaf ears and lots of folk don't understand the proper, British, term. 1 Link to post Share on other sites More sharing options...

ejstubbs Posted May 26, 2021 Share Posted May 26, 2021 This question has certainly been discussed on RMWeb before, though I can't locate a specific example just now. (It may well have been buried as a bit of thread drift under a wholly unrelated thread title.) See also debates about turnout vs point (vs switch). No doubt in some place or another people have also argued about carriage vs coach, truck vs wagon, loco[motive] vs engine etc etc. So long as it's relatively straightforward to understand what people are talking about I don't think it matters a tremendous amount. Often the context will make it clear whether the person using a term is doing so from the background of professional involvement in the 304.8mm to the foot railway, or amateur interest in one of the smaller scales. As to whether or not it makes one's skin crawl, the word that springs to my mind is "tolerance"... Link to post Share on other sites More sharing options...

Indeed, because an obtuse crossing is only found in diamonds and slips, as opposed to the common crossing, which is much more 'common', as it's found in all forms of point and crossing work. 1 Link to post Share on other sites More sharing options...
SGF Posted May 26, 2021 Share Posted May 26, 2021 If you ever have the chance to inspect the underside of a horse's hoof I think you'll find it looks very similar to the combination of the point, splice and wing rails.

RMweb Premium Compound2632 Posted May 27, 2021 RMweb Premium Share Posted May 27, 2021 On the other hand, googling around, I found one source that suggested the frog of a horse's hoof was named for its resemblance to a common crossing... I expect that can be easily discounted by searching for horse-related use of the word before the railway age. 1 Link to post Share on other sites More sharing options...

DCB Posted May 27, 2021 Share Posted May 27, 2021 A lively discussion regarding the virtues of live frogs versus dead ones is almost guaranteed to give one precious space in a crowded pub or on public transport, it's like a pass word or chat up line for suspected fellow modellers, "Do you prefer dead frogs or live frogs?" I suspect early crude single blade points didn't have a frog, just a pivot for the single blade, so it would be interesting to find conemporary references to trackwork from the earlier period to see if the term "Frog" was used. I guess the terms "Crossing Nose" and "Crossing Vee (or "V") mean the same thing. The term "Fishplate" was certainly a later term again misused by modellers, as early rails joined in a joint chair which made keeping accurate rail alignment was difficult. Thus joining rails between chairs became the norm and was known as a "Fished Joint" probably because of the shape of the pairs of "Fish Plates" blothed together to through the rails to join the adjacent rails. Why are modellers wrong? Because the fish plates are a pair one inside and one outside the rail bolted through tightly and not a single piece into which rails slide. The RTR model versions are rail joiners and my blood boils every time I hear the term "Fishplate" misused. (Only joking, life's too short) Link to post Share on other sites More sharing options...

RMweb Gold The Stationmaster Posted May 27, 2021 RMweb Gold Share Posted May 27, 2021 Going back to the original question I think i might possibly have found the culprit although, in fairness, he might not necessarily be the originator of the misuse. In his book 'New Developments In Railway Modelling', first published in 1947, Edward Beal - often regarded as a father of smaller scale railway modelling - uses the term 'frog' when he means 'crossing'. But he does refer back to older articles in 'Model Railway News' (to which he was himself a prolific contributor). However Beal was, so I understand, widely read on the subject of smaller scale (basically OO) modelling so if he did not come up with the misuse he no doubt played a role in widely disseminating it. To what extent Beal was influenced by American railway modelling publications I don't know but it might possibly have been the case that they were how he came to use it? Perhaps from that usage by Beal any manufacturers, and others, then used the term because people understood what it was from Beal's writings? Interestingly all the books I have.on a general approach to, or about, prototype railway matters going right back to the 1930s all use the correct British term (if they had been written in Britain). 1 1 1 Link to post Share on other sites More sharing options...
RMweb Premium RichardT Posted May 27, 2021 RMweb Premium Share Posted May 27, 2021 (edited) Fishplate I have always understood to be ultimately derived from ficere in Latin - to fix or fasten. Hence the “fish” - a strengthening piece for a ship’s mast - which Wikipedia claims as the direct ancestor for the term “fishplate”. Frog (as in the bottom of a horses’ hoof) I have always understood to be derived from its resemblance to the V-shaped splayed foot of a frog (the amphibian). Its connection to railways or wagonways then arising as an analogy by the blacksmiths making early railway track, who, of course, were familiar with horses’ hooves. As such it may well be the original term, rendered archaic in the UK as PWay engineers developed their own specialist vocabulary, but preserved elsewhere. Of course all the above may be so much folk etymology: must do some diggging in old printed sources. This is one of those areas where the internet is useless, as search results just throw up multiple webpages going round in circles because they all link to each other!

RMweb Premium Compound2632 Posted May 27, 2021 RMweb Premium Share Posted May 27, 2021 Looking at the Oxford online definitions of "frog", the common crossing sense is lumped in with other senses such as a florist's frog or the frog on the bow of a stringed instrument, all of which may be influenced by Italian forchetta or French fourchette, meaning "small fork". 1 Link to post Share on other sites More sharing options...

The UIC Lexicon is interesting in the fact that it is a technical railway publication but its English language translation of 'coeur d'aiguille' is shown as 'points crossing (frog)' although in its English reference pages it also list under 'frog' the term 'rerailing ramp (frog)' - possibly it was also aimed at those who use US railwayspeak?. Maybe if we're really into foreign language versions we should go Dutch and just call it 'puntstuk'? 2 Link to post Share on other sites More sharing options...
