We live about a mile from the railroad, and other than disposable dust-mask-style “respirators” this is something I haven’t done. For such a thing to be useful to me there’d have to be: - Some kind of hazmat incident with the train
- That wasn’t quickly lethal to us
- But would be more slowly dangerous
- That we’d be able to escape the dangerous zone if we found out about it in time
- Where respirators significantly increased the safety of our escape
The “escape” factor is not a small one — will roads be passable? Will whatever happened prevent my car from operating? Would our clothes be contaminated such that we needed a hazmat response? For my family this seems like a big expense for a very small likelihood of needing it.

A respirator, or at least an N95 disposable mask, is a handy item for many situations - standard equipment

Why limit concerns to just trains? Many interesting things are hauled by motor freight on highways and city streets, even right next door....

A respirator is the last line of defense, and it's a lousy, limited one. A half mask or full mask, with a P100 particulate plus chemical, is a miserable thing to breathe through. If the user is not trained in its use and fit tested for a reliable seal, it's basically a fancy condom with a hole in it.
Emergency services and the railway will have a plan, in some detail, for such a contingency. They won't hand you the full plan because it contains personal data, names and phone numbers etc. But if you ask, they will usually give some guidance.
One of the biggest practical measures will involve having the local populace shelter in place. And that is the place to invest time and dollars -- making your residence and your shelter room as airtight as possible before an incident.

Keep duct tape handy. I am reminded of an incident here on the Channel islands (California). A missile launch at Vandenberg AFB went awry and it exploded on the launch pad. San Miguel island was directly downwind. The people on the island went into the Ranger Station, basically a CONEX box with a couple of doors and windows, and sealed the opening with duct tape until they could be flown out.
No fun at all....

Not sure how this is in other places, but in my country train and road have specific corridors for hazardous materials. These avoid things like tunnels and densely populated area's.
In many cases the type of materials transported in large quantities are known and can thus be prepared for.
Do note that there outflow of any goods are limited by the amount present. That gasses will get in to building; thus ventilating after a cloud of gass has passed is important.
