"... a range of values" or indeed a range of trains (e.g. https://www.eba.bund.de/DE/HauptNavi/FahrzeugeBetrieb/Fahrze... But I wouldn't have /thought/ that is the intention here ...

Cilian O'Tuama Feb 3, 2017:

The Bandbreite seems to be measured in minutes so Alison's Zeitfenster is looking good, although the Bandbreite is half the Zeitfenster.

phillee Feb 3, 2017:

It does look like the rail industry might use the word Bandbreite to signify a range of values rather than an amount of throughput. Really need to know the specific value they are referring to.

polyglot45 Feb 3, 2017:

I'll admit to a measure of guesswork lack of context doesn't help but I have translated this sort of stuff in the past and have a pretty good idea of what is going on. Admittedly "Bandbreite" sounds like in-house engineering jargon and it would be as well to ask the client

Alison MacG Feb 3, 2017:

See also Durch Rahmenverträge wird somit Sicherheit hinsichtlich der Verfügbarkeit von Schienenwegkapazität innerhalb eines im Rahmenvertrag festgelegten Zeitfensters (Bandbreite) über einen Zeitraum von mehreren Jahren bewirkt.
die vereinbarten Bandbreiten (Zeitfenster)
https://www.bundesnetzagentur.de/DE/Sachgebiete/Eisenbahnen/...

Ein Rahmenvertrag verschafft dem Zugangsberechtigten bei Trassenkonflikten eine gesicherte Position. Zwar kann nicht eine konkrete Zugtrasse vereinbart werden, es kann jedoch eine Bandbreite festgelegt werden (z. B. für die Relation A – B Abfahrt 7:30 Uhr, Ankunft 8:00 Uhr mit einer Bandbreite von +/- 10 Minuten; dies entspricht einem Zeitfenster von insgesamt 20 Minuten), innerhalb derer dem Zugangsberechtigten ein Angebot auf Zuweisung einer Zugtrasse zu machen ist. Dies bedeutet, dass dem Zugangsberechtigten innerhalb der vertraglich vereinbarten Grenzen eine Zugtrasse zusteht.

We're just guessing here. There's no way of knowing without more context, which Barbara may not have.

polyglot45 Feb 3, 2017:

phillee Feb 3, 2017:

If my hunch is correct, it would be something like
"secure access to the tracks necessary to fulfil the capacity requirements"

polyglot45 Feb 3, 2017:

not command/control if it is S-Bahn ICE perhaps but then that is not the topic it would seem

phillee Feb 3, 2017:

Sounds to me like they need to secure enough slots on the rail routes in order to provide the required passenger capacity.

Barbara L Pavlik (asker) Feb 3, 2017:

@polyglot45, they are regional passenger trains, including some S-Bahn service.

phillee Feb 3, 2017:

Capacity Possibly referring to the number of trains that can pass through the route in a specified time?

philgoddard Feb 3, 2017:

It doesn't just mean bandwidth. Flexibility is another option, and a dictionary would probably provide more.

polyglot45 Feb 3, 2017:

what sort of trains are these? High-speed, freight it could indeed just be that services that failed to go through as planned have to be replaced by the contractor providing the necessary train paths "Zugtrasse" via a framework agreement etc., while making allowance for the scale of the path OR - and perhaps more likely - the band widths needed for the train control/command system - it is very ambiguous

Edwin Miles Feb 3, 2017:

I'm guessing... they mean something along the lines of "scope".
