Pod trains
Yeh, personal pods, I always thought that would be a neat idea.... have a little slow personal pod for moving yourself and your stuff around, then have trains of pods with a bigger engine to ship the pods longer distances.
Don't stop the trains to add/remove a pod, accelerate a mod down a ramp, attach it to the end of the train in motion. To remove the pod, decouple, sideline the pod, recouple, or if it's at the end, just decouple.
