I have talked about this cammera with some swiss train enthusiasts in switzerland and we came up with its 3 flaws.
1) It is facing one direction and the 460 seires (most swiss loco's for that matter) can be used in both directions so often you only see that back of a car.
2) the slow update time. Instant would have been neat but trying to run streaming video wirelessly off of a locomotive in not easy or cheap.
3) The software is awfull and the thing freezes or crashes all of the time. Also we noticed that the time is always incredibly wrong
Its cool none the less.
