French term or phrase:butee basse
"Les suspensions sont en butee basse ce qui interdit l'inclinaison caisse"
and the second one is
"les deplacements verticaux se superposent aux deports geometriques dus au
passage en raccordement de profil"
Explanation: I can't figure out whether your "en butée basse" is a part of the train car, or something outside the car, that would keep its suspension on an even keel when stopping. I've looked for I've "suspension en butée" and can't find any such animal on Google! I followed up on both previous answers, "down stop" and "bumper stop," relating to trains and/or trams, and both terms, while applicable to trains, appear to refer to external items:
1. "Bump stop"
"BUFFER STOP Structure at the end of a track to prevent vehicles proceeding off the end of the line. Sometimes these are cushioned by hydraulic rams or protected by emergency braking devices such as a sand trap. In the US known as a ‘bump stop'." http://www.trainweb.org/railwaytechnical/newglos.html
Note that "buffer stop" would be the UK term. And I do get a fair number of hits on Google for that term. See:
2. "Down stop" (And I found a site with an actual photo!) Just use your search function to find the term (about ½ down the page).
And thanks for asking this question: Woburn is a place I actually used to travel through as a child, back when the locomotives pulling the trains were steam-powered! I hadn't thought about those stations in a long, long time! It's nice to have a term to attach to that particular part of the railway landscape.

Note that the (really wonderful!) GLOSSARY OF MODERN RAILWAY TERMINOLOGY gives the following for suspensions. If you really need a term for a part of a railcar suspension, you'll find it here. I wonder, in particular, whether "spring plank" (part of the secondary suspension) might not be the term you are looking for.
On a railway bogie, the flexible interface between the vehicle axle and the bogie frame. It can consist of steel leaf or coils springs or rubber blocks.
The flexible interface between the vehicle body and its bogies. Like primary suspension, it can be steel or rubber and is now, in addition, often composed of an air cushion system employing rubber bags or air bags.
Originally, steel springs were used. In UK practice, they were mounted on a transverse beam known as a spring plank. Guides and shock absorbers were strategically placed to ensure stability. Such systems can still often be seen today and there are many variations on the theme. http://www.trainweb.org/railwaytechnical/newglos.html
