The Railway team has introduced a new feature called Metro, which allows users to deploy multiple services within a single project, improving organization and project management. This feature includes the ability to create multi-service templates, where users can configure environment variables, start commands, and healthcheck paths for each service, making it easier to deploy monorepos. Users can also generate templates from existing projects and manage their templates through a new interface. The Railway team is now accepting feature suggestions and invites users to share their ideas on how to improve the template feature.
