Proposal

This proposal defines a single key that supports all train protection systems, easing tagging and data processing.

Values will be of the form ^(PREFIX:)?(NAME)$(pseudo regex) or no and are separated by semicolons, the PREFIX being either a country code or "VND" for vendor systems.

Example:railway:train_protection=PZB;LZB;ETCSThis would be a "full-featured" installation in Germany using both the PZB and LZB systems as well as the European system ETCS.

Train protection version specifications would be moved in a subkey, e.g. railway:train_protection:ETCS=1;2separating the values with semicolons, too.

Rationale

Currently, every train protection system is tagged using its own key inside the railway namespace. Existing tags:

• Key:railway:pzb
• Key:railway:lzb
• Key:railway:etcs
• Key:railway:gnt

This has the disadvantage that deciding if no train protection system is installed on a given line means checking _all_ of these tags for being absent or existing and having the value "no". The number of checks grows for every country specific train protection signal being added.

The names of the train protection systems are often abbreviated to 2-4 letters. It is highly plausible that there will be collisions between different countries using the same abbreviation for different systems. These tags could also cause future collisions with different things in the railway namespace that would use the same abbreviations.

Tagging

This table is taken from OpenRailwayMap/Tagging. That section would be removed from that page and would redirect to the new key page.

The table was a brute force mapping. Some vendor systems are not yet specified how they should be mapped, this will likely affect especially unconnected railway installations like airport monorails or things like that. See discussion page.

US:E-ATC	likely tagged as railway:ptc	yes/no	Enhanced Automatic Train Control	Is the track equipped with the North American Enhanced Automatic Train Control system? Note that while this is also a cab signal overlay type of positive train control (automatic train protection) system, it is distinct from and largely incompatible with the ACSES system mentioned above. It should also not be confused with legacy Automatic Train Control systems, which have been replaced by either E-ATC or I-ETMS.
US:I-ETMS	most I-ETMS is tagged as railway:ptc	yes/no	Interoperable Electronic Train Management System	Is the track equipped with Wabtec's Interoperable Electronic Train Management System? (This is the standard Positive Train Control system used by the US Class 1 freight railroads as well as most commuter railroads and shortlines outside the Northeast Corridor that are required by law to fit Positive Train Control; there are a few commuter lines and shortlines that use E-ATC instead though.)
US:ITCS	railway:itcs (may also be tagged as railway:ptc)	yes/no	Incremental Train Control System (ITCS)	Is the track equipped with the North American system GE Transportation Systems' Incremental Train Control System (ITCS)? Note that there is only one ITCS install in the US, and that's on the Amtrak/MDOT Michigan Line.
US:PTC	railway:ptc	yes/no	Positive Train Control	Is the line equipped with a train protection system that meets the US Positive Train Control standards? Note that this value should not be used if another train protection value is present, as that more specific system is presumed to be an implementation of Positive Train Control, not a separate system.
no	N/A	N/A		Is the track lacking any train protection system?
