Hi Mr_Spritey,

It looks like you've traced some new segments of Interstate 69E. I checked the imagery you used here, and I could only see it under construction.

Can you confirm that you've traveled down this road and seen it yourself? Otherwise, can you link a news article about these new segments?

Hi Russell722,

Again, please leave a message when you revert someone's edits, or at least a more descriptive changeset comment.

I changed this segment of US 59 Business to primary because it does not serve as a long-distance route. Through traffic generally follows US 59, which is already tagged as trunk. In good faith, I've reverted the business route back to primary. Let me know if you have any questions.

Hi Russell722,

It looks like you reverted my edits without notifying me. Typically it's polite to leave a message when you do this, or at least a more descriptive changeset comment than "Edited roads."

I changed this segment of US 259 Business to primary because it does not serve as a long-distance route. Through traffic generally follows US 259, which is already tagged as trunk. In good faith, I've reverted the business route back to primary. Let me know if you have any questions.

Top speed for the Sprinter is 50 mph, and top speed for SMART is 79 mph. Those are tagged as `maxspeed=*` on the underlying tracks. Does light rail have a speed restriction that I'm unaware of? Are there any public transit routing services that are affected by this change? Which data consumers are using this data?

Most of the criteria you listed (distance, speeds, track configuration, stations) are orthogonal to whether a railway is considered light rail. The rolling stock for SMART is much lighter than conventional trains and not FRA-compliant. Because of this, certain segments of track are restricted to DMUs, and FRA-compliant trains must wait until they're all off the tracks before they can make any movements. The rolling stock lacking FRA compliance points to "light rail" to me. They may only operate on their special track and can't continue onto the rest of the conventional rail network.

Again, SMART could reasonably go either way, and I'm happy to do the work to retag it to conventional rail. If you live in the North Bay, and SMART just intuitively "feels" like conventional rail rather than light rail, that's convincing enough.

This train station was not "added" in this changeset—it was deleted elsewhere and this building was retagged to become the train station.

Unfortunately this changeset introduced a few tagging issues. For example, the NJ Transit train station at Union was already properly mapped as a node, and shouldn't have been merged with the station building. The building is a part of the station (building=train_station), not the station itself (railway=station). Also, "Train Station" is unnecessary in the name of a train station.

This changeset also brought in an improperly mapped multipolygon for the railway platform. A platform does not cease to be a platform when it is covered by a roof, therefore a roof should not be a member of a surrounding platform multipolygon relation.

Let me know if you have any questions. I know it's probably frustrating, but I hope it doesn't discourage you from editing. Most of the work you've done in the area seems good and well-detailed.

So SMART is an oddball. It's a temporally restricted passenger railroad, like the Oceanside-Escondido Sprinter and certain lines of the San Diego Trolley, where freight movements are only allowed when passenger service is shut down. The consensus is, when light rail is temporally restricted, the tracks that support freight rail should be `railway=rail` and the passenger-only tracks should be `railway=light_rail`.

Though that doesn't answer the question of whether SMART is light rail. Realistically, it could go either way. It's got the characteristics of most DMU hybrid light rail lines, but it's a bit longer and its service pattern is more commuter-oriented, with no trains for a couple of hours between commute periods. Tagging it as conventional rail would probably work just as well.

Perhaps this needs more discussion on the mailing list or Slack. This is an edge case and I'm not sure what's best here.

Hi Steve - I thought we had a discussion on this months ago. Shouldn't these ways remain `railway=rail` and not `railway=light_rail`? Light rail vehicles can travel on temporally restricted `railway=rail`, but freight trains can't travel on `railway=light_rail`.

Hi - I'm on vacation for a week. I'll take a look at this when I'm back.

Hi ironmatic1. usage=tourism is a documented tag with extensive use. Tracks can indeed be tagged as usage=tourism, regardless of whether they show up on OpenRailwayMap. If they don't show up, that is a problem with OpenRailwayMap's renderer and not with the underlying data. I've gone ahead reverted these tracks to usage=tourism.

Hi Nick,

The platforms at Clybourn were intentionally divided down the middle to preserve information about which routes stop on which side, as well as avoid creating multipolygons. Technically it could be mapped either way, but as a railway mapper, I find it easier to maintain when platforms are mapped as ways without multipolygon relations. I hope you don't mind me changing it back.

Oops, should have been under my personal account

The LA Metro G Line is not a guided busway. A quick read of the wiki page for busways could have prevented you from making this mistake: osm.wiki/Tag:highway%3Dbusway

Honestly there wasn't much thought behind it. I put it in that order because I felt US 62 was sort of a hodgepodge of other roads that formed a neat grid. It doesn't reflect any on-the-ground reality.

No worries! Just curious. I went ahead and reverted it.

Why did you change the Metra 47th Street Yard from railway=service_station to railway=yard? This facility does not handle freight.

Hi Nick,

Could you explain what the ref value of "FAP 370" represents, and why it was applied on such a short segment of Western Boulevard?

In the future, please use more descriptive changeset comments than "adding details". Consider being more specific on what kinds of details you're adding. If you can summarize what you've worked on, it saves a lot of time and effort on the part of other mappers.

-Clay

It could, but it'll simply be re-added shortly after by someone else. If you choose to keep deleting things that exist in the real world, like this driveway, you may lose your permission to edit again.

Sorry to inform you, but there's really nothing you can do about that.

No worries, thanks for understanding.
