That's accurate. Train is the version with both CentOS8 and CentOS7, while
ussuri is CentOS8 only.

You can start using RDO Trunk Train for CentOS8 repo already configuring
following repo files:

https://trunk.rdoproject.org/centos8-train/delorean-deps.repo
https://trunk.rdoproject.org/centos8-train/puppet-passed-ci/delorean.repo

About CloudSIG signed packages in CentOS mirrors for Train in CentOS8 we
are still working on it, We'll update on this ML when ready.

You can find some info about RDO moving to CentOS8 in
