Due to the uptick in bad faith posters, we have added new sub rules that will make it easier for you to browse and for us to moderate.

Currently we have three simple rules:

1 - Submissions must be subway related.

Posts and comments must be related to the topics of Subways, Metros, Undergrounds, or U-Bahns.

Interurbans and Light Rail systems may also be mentioned, if they have sub-surface sections.

2 - Submissions must be unique.

Any reposted submissions will be removed to keep our content fresh and unique.

3 - Comments must be on-topic.

This is a space for discussing trains that go under the ground. Any conversations that stray far from this topic will be removed.

If you come across a post or comment which you think violates any of our rules or reddit's site rules, please report it and it will be dealt with.

For the time being, posts with a city flair from Russia or Ukraine will have comments auto-locked.

Thanks!
