Air or steam brakes
Air or steam brakes
My locomotive has steam brakes on the engine and no brakes on the tender. I am looking at adding straight air brakes to the tender and probably the whole train. Is it worth it to convert the locomotive brakes to air? Is it difficult and is it worth it?
Thanks

Re: Air or steam brakes
Keep the steam brakes on the engine. They can be used a backup/emergency if the air brake line goes out or if you are just moving around the yard without the rest of the air system.

Do the steam brakes work? If so…the old adage applies, if something works…DON’T Fix It.

Re: Air or steam brakes
steam brakes work as a parking brake more then anything, they tend to be slow to respond when the system loads up with water.
if you will be adding air brakes. its real easy to convert the locomotive over to air.
I personally run straight air on the loco, tender, the train is auto (failsafe).
the pacific, I am looking at straight air on the locomotive only and auto from the tender back.
still have the redundancy, but personal experience, I rarely use the straight air brakes while on the main. its easy to just do a 5 to 10 reduction when controlling or stopping the train,,, or big hole it when some idiot is not flagging their train around a blind curve

If it is not live steam. its not worth it.

Re: Air or steam brakes
Having two different brake systems is a plus in case of a failed compressor, battery, etc. I would keep the steam on the engine and go with straight air on the tender.
Another issue is straight-air .vs. automatic air (more complicated) but that's another discussion and depends on your preferences, train length, etc.

Re: Air or steam brakes
I second, or third, the keep the locomotive steam. You’ll have a backup in case something happens, plus that’ll save wear on the locomotive brakes and tires.

Re: Air or steam brakes
Keep the locomotive brakes steam, and independent from the brakes behind.

Re: Air or steam brakes
I think it also depends on if you have enough room in your tender to have an electric air pump, battery, etc. I certainly wouldn't change what is already there unless there is a problem, but if a new build, and the loco/tender are large enough to not rely on a trailing car for the compressor setup, then there is no reason not to use straight air on everything since it's all self contained in the locomotive/tender.
If it's a smaller locomotive and you would need a trailing car to contain it all, then I'd absolutely want steam brakes on the engine otherwise you will have no brakes without your "brake car".

Re: Air or steam brakes
unless you have a huge tender, you are going to need a 'support car' for the air compressor, tank and battery'....
Dave's example of what to do is a good place to start...totally separate car.
keep in mind that these little compressors tend to be noisy, so you will need to spend more time than you have planned on noise-abatement

Too many things going on to bother listing them.
Re: Air or steam brakes
Air would be more easily modulated than steam. At 40PSI I've got good braking action and at 60 PSI the drivers start to lock up.. so a conversion to air would easy aside from the source.. I considered converting mine from steam to air but I'm starting to add brakes to the cars and will leave the locomotive independent.
It's more fun pulling cars down grade than being pushed by them.
