Boiler question

[digiartst]

OK in the book the "The Locomotive enginmans manual" it says under certain situations , the 2-8-2 can and should have its fire dropped and boiler blow outs released to immediatly drop steam pressure to avoid explosion hazard(for various failures.
Then the problem field repaired if able. Now to me with the boiler drained and the fire dropped. there would be no way for the injectors to work.Now the problem is refilling the boiler and restoking the fire.
. My question is did the tender have a hand pump to be able to hand fill the boiler in the field after a repair was done on the fly?(I have never seen a reference to this pump if it exists in any of my reference material I own but it makes sense to me ). I know a tender is also gravity feed but it would be a slow process since all the feed goes through the non functioning injectors and the 2-8-2 injectors are actually higher than the tender water level. This is an emergency far away from home, repair and get the steam back up situation I am talking about.
Also what type of repair stuff was carried in the tender tool box. The book says to carry a few railroad ties and lengths of chain on the tender for repair was common practice but what else was carried for field repair.
Anyway this book and no book I have tells me the proceedure for a cold start of an engine , basically it says it is a multi hour practice not performed by the engineer.

This is just a curious hey how do the do that question not a brain buster



Thanks

I'd say you'd close off the blowdowns after all or most pressure was relieved, one should be able to rebuild a fire with what water remains if level is high enough. If not, a external water source with a decent pressure would be required until you have sufficient pressure to have the injectors working, more or less. I'd say common practice would be to send a replacement locomotive, however, since it takes around two or three hours to get pressure and a fire back up.

Cold Start Procedure for a coal burning engine (more or less, this is with no water in boiler and nothing on the grates):
1. begin filling boiler with water (external water source of some sort)
2. begin to spread a layer of coal over the entire grate area
3. when water level is sufficient, light coal using wood kindling and scraps and fluids of some sort (diesel fuel works great) and also a draft fan.
4. continue feeding the fire until it has spread throughout the firebox and until working pressure is reached and maintain it.
5. turn on appliances when their minimum pressure is reached as necessary and perform any other locomotive maintaining duties or inspections (i.e. oil, grease, wash ashpan, water down coal, etc.)
