Given the technology requirements and operational factors of procuring and operating a UAS like this, which is current completely illegal anyway, once per day, it would be a non-starter. Send a guy down the line in a hi-rail truck. Done.

As I said before in the above linked article, drones are already legally in use by at least one Class 1 Road:

http://fortune.com/2015/05/29/bnsf-drone-program/

After years of accusations of foot-dragging on unmanned aerial vehicle (UAV) regulation, the Federal Aviation Administration has recently been speeding exemption approvals and announcing new regulatory programs. One beneficiary is BNSF Railway, which has gained approval for a pilot(less) program to use drones to inspect its far-flung network of rails. The inspections could help reduce derailments and other safety problems—and though BNSF isn’t saying so, lead to lower labor costs in the long run.


Ron: the truck is cheap enough, not the crew. I’m not saying I want people out of a job either, but to be honest BNSF is saying exactly that.

That article is misleading and some points are completely wrong. Nor does it satisfy what this thread is suggesting. BNSF does NOT have an exception to operate beyond visual line of sight. The aircraft must be within visual line of sight of the operator and a visual observer (both). This does not allow the drone to do anything meaningful other than some testing and development work. The concept of a drone cruising along a railroad to inspect the track is not currently legal, and no railroad has the legal authority to do anything even remotely close to that.

But it does have said authority as part of the FAA Pathfinder Program. The FAA touts BNSF as its launch partner for BVLOS drone testing.

Beyond visual line-of-sight operations in rural/isolated areas
BNSF Railway will explore command-and-control challenges of using UAS to inspect rail system infrastructure.

Here's a better idea: a robot running on the tracks *just* far enough ahead of the train to trigger auto-braking, but not entering the crossing until 5 seconds after the gates are down.

Put a camera on the front that the engineer in the following train & dispatch staff have continuously on-screen, Roomba-like sensors on the bot itself to detect collisions, and the usual accelerometer & gyro monitored for unusual motion. Make the bot big & heavy enough to dent a car it hits or take off the bumpers, but not so big that it becomes dangerous itself.

Advantages:

* much, much cheaper to engineer a rolling robot the approx. size of a golf cart chassis able to run at speeds up to 180mph day after day than to build a drone able to survive that kind of a daily beating.

* plenty of cheap all-day power. With a drone, every gram is precious. A high-powered 180mph glorified semi-autonomous golf cart on track-sized wheels can carry lead acid batteries... or 30 gallons of diesel or kerosene.

I might be wrong, but I could *swear* I remember reading somewhere that JapanRail already *has* robots to do frequent track inspection.

This kind of device already exists, more or less: http://www.rail-pod.com

Per the photos on the link provided, the rail-pod is trailered to the inspection site; so the range can't be far and speed must be pretty slow. It doesn't quite match what the original poster wanted, a scout running in front of trains at speed.

Flying drones ahead of trains. Lmao, this is the most absurd idea I've read yet. It would cost too much and as 8thNotch stated at the beginning of this discussion, what if something happens between the drone and the train? The costs would be enormous. Who would monitor the surveillance screens? There's also the delay in communicating any events to the trains.

Why not just install lazers on crossings instead? if the lazer breaks, it alerts dispatch. You then place the level of the lazer high enough to avoid being interfered with by snow.

I'd suggest looking at more than photos--it goes pretty fast and has a pretty long range. It may need some upgrades to go before intercity passenger trains at speeds close to theirs, but it could otherwise do what the original poster suggested, at least for freight.
