Talk:Key:trolley wire

electrified

Es mag sprachliche Überschneidungen geben. Aber bei OSM wird trolley_wire auf Straßen angewendet und electrified auf Gleise. technisch gibt es auch mindestens einen deutlichen Unterschied: trolley_wire hat 2 Drähte und die Bahn hat nur einen (die Gleise sind der Rückleiter). Da sich das bisherige gut bewert hat sollten wir in diesen Fall keine Änderung anstreben. (Sorry for the german you can translate it if possible.)--geozeisig (talk) 07:13, 25 February 2018 (UTC)

Google translate: "There may be linguistic overlaps. But at OSM, trolley_wire is applied to roads and electrified on railways. technically there is also at least one significant difference: trolley_wire has 2 wires and the track has only one (the tracks are the return conductor). Since the previous good rating, we should not aim for a change in this case. (Sorry, you can translate it if possible.)" Mateusz Konieczny (talk) 07:32, 25 February 2018 (UTC)

I removed cleanup template, I see no reason for it exists. Somebody who is not bothered enough by tagging issue to post on tagging mailing list should not edit wiki to add some horrible templates Mateusz Konieczny (talk)

Could someone please tell me the difference between a way tagged with highway=tertiary + electrified=contact_line and a way tagged with highway=tertiary + trolley_wire=yes? --Klumbumbus (talk) 10:21, 25 February 2018 (UTC)

No idea - is there some technical difference between wires for tram and wires for trolleybus? Mateusz Konieczny (talk) 22:41, 25 February 2018 (UTC)

contact line is like tramway, trolley uses kind of half-pipe which must be put under the line (electrical line goes into tthat "pipe")--przemas75 (talk) 12:51, 9 June 2018 (UTC)

If you mean the type of contact between vehicle and wires: Trolley wires were first deployed on railways (at first tramways but mainlines and interurbans also started with these) before expanded to buses and by that logic, you'd use trolley_wire=* and not electrified=* for tramcars which still use a contact shoe and not a pantograph (they're even compatible with each other, although I haven't found an image thereof at least on commons), not to mention that pantographs also have been experimented with road vehicles. The only difference between road and rail electrification is that rails can (and often — but not always(!) — do) carry the return current whereas roads can't, thus necessitating a second wire. —Preceding unsigned comment added by ManuelB701 (talk • contribs) 07:04, 2025 July 16

Another question, in Gdynia (probably many other cities) we have trollebus with trolley wires, but also the same trolleybus uses batteris at the end of trolley line, i dont have a clue how to tag, osmi validator claims there is no trolley_wire, but this is ok, as vehicle moves using batteries... --przemas75 (talk) 12:51, 9 June 2018 (UTC)

In this case I would report overzealous validator at JOSM bugtracker using https://josm.openstreetmap.de/wiki/Help/Action/ReportBug Mateusz Konieczny (talk) 16:03, 9 June 2018 (UTC)

Yes, this is also a problem in other cities. Maybe we could add some special tag like battery_operated=yes to the trolleybus routes (relations type=route) that are operated by vehicles with batteries, and for these relations the OSM Inspector could skip this particular check.

What redundancy with trolleybus=yes ?

I don't see the redundancy mentioned on the wiki page. trolleybus=yes means a trolleybus stops at the marked public transport stop. trolley_wire=yes means there are electric wires mounted above the road. It does not mean any trolleybus necessarily drives (less so stops) through there in years. Just that it is possible to do so. route=trolleybus relations say whether any trolleybus lines drive through there regularly. —Preceding unsigned comment added by Aceman444 (talk • contribs) 12:49, 22 June 2025
