I've put 6 personal roboports in my construction wagon, which yields a 73x73 construction area. But it seems like the wagon is limited to 30x30, which is the default for a roboport.
This is an issue as I wanted to use the train for expanding my rail network, but with a limited area of 30x30 I have to manually move it so often as it constructs the rails it's driving on.
Overall I love the concept and I'm enjoying the mod.
