Proposal:Transit energy source details

Transit energy source details
Proposal status:	Draft (under way)
Proposed by:	Kovposch
Draft started:	2021-10-03

Proposal

Adopt generator:*=* tagging on route=*. This goes with Proposed features/Alternative energy focused power revamp.

electrified:collection=* will be used on both railway=*/highway=* and the route=*.

Rationale

It is more straightforward to adopt power=generator tagging than to invent something else again for a new application in another feature.

• trolley_wire=* on highway=* for trolleybus=yes (at least for non-battery sections) overlaps with electrified=contact_line on railway=* to some extent
• "trolley" in trolley_wire=* can be confused as a synonym of tram/streetcar, although indeed trolleybus can share with them.
• electrified=contact_line doesn't indicate whether single-wire trolley pole, or rigid overhead conductor rail, are used; or whether batteries or fuel cells are used, when electrified=no sections exist.

This proposal doesn't cover whether a route=train uses loco-hauled or multiple-unit trains.

Tagging

Electrification

Could be applied to roads for charging buses.

• electrified=inductive Inductive power or charging
• contact_line=* Detail of electrified=contact_line
  • contact_line=wire
  • contact_line=rail  Overhead_line#Overhead_conductor_rails

(To-do: Cable details, to pick up on OpenRailwayMap/Tagging and refer to Proposed features/Lines attachments et al; trolley bus twin wires)

• electrified:collection=* current collection device
  • electrified:collection=pantograph
  • electrified:collection=trolley_pole
  • electrified:collection=shoe Overlaps with electrified=rail and electrified=4th_rail
  • electrified:collection=coil Overlaps with electrified=inductive

trolley_wire=yes will be treated as electrified=contact_line + contact_line=wire + electrified:collection=trolley_pole

• electrified:function=* The purpose of electrification
  • electrified:function=propulsion is assumed by default
  • electrified:function=charging on short sections of Battery (BEMU) or supercapacitor train lines
  • electrified:function=maglev to power the on-board magnet or primary-side
  • electrified:function=services on-board non-motive equipment only
• voltage:left=* and voltage:right=* for electrified=4th_rail

On-board generation

• mechanical_transmission=* The transmission system
  • mechanical_transmission=electric Eg diesel-electric
  • mechanical_transmission=mechanical Eg diesel-mechanical
  • mechanical_transmission=hydraulic Eg diesel-hydraulic

Energy source

• fuel:*=*
• *:compressed_air=*
• *:engine=*
