It seems to me that DTG have lost interest in Journey mode. First they exclude it from quick play and dynamic weather. Two of the big selling points of TSW3. Now they release new content which doesn't even have its own journey mode. IIRC the last content which didn't include a journey was the 155? Personally I really enjoy doing the chapters as they always give a varied and interesting mix and I don't have to think about what to do next on a route until I finished them by which point I know what I enjoy and don't enjoy on each route/loco.
