I’m sure I will be called an idiot by enjineerz for this, but I know I’m rite:

Brakes for trainz that match the mass and speed requirements! 

Any vehicle thats likely to encounter unforseen obstaclez shoud be able to stop in a reazonable distans to avoid a colision. ESPECIALLY vehiclez that cant chanje their direction. 200 ft maximum from 70 mph.

Currently it takes sumthing like a mile to stop a fully loaded frate train. Rediculous! Probably the yung wippersnapper enjineer traineez think uv this every time therez a fatal accident in the newz and the senior enjineerz call them idiots and go back to dezining A LOUDER HORN!

And I dont know wut the orijinal idea with the 4 ft wide tracks wuz, but 10 ft wide x 20 ft tall trainz need to hav tracks AT LEAST 12 ft wide. Az with alot uv the foolish Earthling foolishness, its probably tradition, in this case going all the way back to the 1804 Penydarren Tramroad. You’d think that sumtime soon after, sum jenius railroad enjineer woud think ‘wider = less tipping over and killing everybody!’

A  particularly stoopid frend uv mine believez that the fault liez entirely with the driverz who get hit in crossingz.

Even tho its usually true that they make the mistake that iz the immediate cauze, they are really only presipitating an event out uv conditionz that are set up to make it likely.

the entityz in control uv the infrastructur hav the responsibilty to take all the real world factorz into account. Wun uv thoze factorz iz that humanz often make bad desijunz.

Over a long time line across the country or the entire world, you woud probably find a fairly stedy rate uv occurans and cost for theze bad desijunz and be able to factor them into a cost/benefit calculation to justify the expens uv sum level uv braking system.

Exectivez and the company lawyerz just blaming driverz all the time iz a failure uv their duty to the society that payz their jenerous (probably exorbitant) salaryz.

Plus, its not alwayz the case that the vehicle gets hit due to an error uv its driver.

Sumtimez the car or truck behind pushez it onto the tracks. Sumtimez snow or ise cauze it to looz traction. Sumtimez there are pot holez or the ground sinks, cauzing a vehicle to bottom out on the railz. There are crossingz next to street intersectionz where the lites and gates are not coordinated properly. Sumtimez a pedestrian or another vehicle duz sumthing that requirez the vehicle to stop on the tracks.

We are living in a world full uv unpredictable situationz wich require vehiclez to hav the power to stop quickly to prevent dizasterz. Trainz are no exeption.

An Obvious Solution

The emerjensy brake system coud be caliperz on every locomotiv and car and a sentr rail they woud clamp onto. Just like disk brakes on a car, exept linear.

Sins most aksidents occur at crossingz, the brake system woud only need to be around them. The rail woud need to be az long az the longest train plus the distans expected for the train enjineer (or automatic radar system) to see that he needz to stop. So a few milez total, much less for commuter only tracks. This woud spred the heat load over a far larjer mass than a rotor like on a car and remove the traction requirement off the weelz.

Therez no new tek involved. This coud hav been dun 200 yirz ago.
