Reviews & Comments of RTT Mapper chrome extension

Excellent supplement to RTT. I never knew how useful this would be until I tried it — with my rail enthusiast's hat on, it's great to get a feel for where freight trains have come from/are going to without having to remember obscure location names. And with my passenger's hat on, it's a great way of seeing at a glance if a service is booked to be diverted away from its usual route, rather than having to scan down the list of calling/passing points... A few remaining data issues that cause train routes to zip off to bizarre parts of the country and back still aren't enough to tarnish this excellent extension.
