German term or phrase: Rattermerkmale
Same test report about tests and checks and measurements on an electric (overhead) railway line, using a computer program.

Something like clatter characteristics ?

Auf derartigen Streckenabschnitten treten dann häufig Rattermerkmale auf. Die Fahrleitung hat an der Kontaktfläche Wellenberge und Wellentäler.

pulsation characteristics
Explanation:
probably caused by an undulating surface where the pantograph tends to bounce. This may have a number of causes ranging from a damp environment as in some tunnels to ice formation on the catenary being broken away by the pantograph's carbon strip, striking an arc as it does so, and burning away a little of the overhead line.

Grading comment
In the context, this makes a lot of sense, as they are talking about precisely the problems of an undulating surface on the overhead line.
Johanna Timm's suggestion was also interesting, but more relevant to wheels, whereas this use of the word in the text happens to be confined to the overhead electric line.
Many thanks to both.

clattering (noise)


Explanation:
just like, that might work.
"I am sure everyone knows that those are caused when the wheel skids on the track and makes a flat metal edge on one wheel, causing a clattering noise. That damages the track and causes overtime. Track can last a long time if it is looked after, but if it is battered daily by wheel flats it lasts less time. They cause cracked and broken rails in time. They also cause damage to the train, but the primary damage is to the track. "
