Alan- "Foamers" is a humorous nickname attached to fanatical railfans. What you call train spotters, over here are railfans. Foamer stems from foaming at the mouth, a reference to rabid, as a level of passion akin to near madness. I typed that in reference to the bunch Kevin noted which had run up to the bridge for pictures.
I am aware of the term "foamers" Ken, but 37's are so good they are impossible to resist. I especially like Kev's videos so we can hear the wonderful sounds.
Uh, uh, didn't know the word "foamer" neither... Anyway I think me too I'm falling in love with these 37s. Furthermore they bring me some reminds, when I spent 3 weeks in the UK in 1979 for a "language journey" (I was 15). I had been very scarcely in UK since then but I remember I had already noticed these units with their bulbous nose and their wonderful growl along the local railroad where I used to spend some railfanning time (already!)... Many thanks Kev for these reminds! And happy to see these monsters are still making the UK railroads shine. One question however: are they used for "true" freight trains (ie else than MOW)? I'd like to see one (or two paired) of them struggling with tonnage on a grade in Run 8... Dom, freight and diesel fan
Kevin will know more, but they are used regularly on nuclear flask movements, usually in a pair. Maybe also on other non MOW workings. They have also been used on the leaf-busting trains in autumn (fall) with water-jet cars to clean railheads.
