In that webpage someone gave they recoommended this:
STIHL Rescue Chain Saw
The chain itself is 160 dollars on ebaay, but look at what it can do.
I hope someone I email this too will buy me one. I'm sure I can find a
use for it.
Compact heavy-duty chainsaw for rescue and emergency services use
The rescue saw Stihl MS 460 RS is a chainsaw designed specifically for
the requirements of the emergency services. The 76.5cc engine power
gives the carbide tipped chain sufficient feed force to cut into roofs
Materials that can be cut include the following:
- Armoured glass - train windows
- Sheet steel
- Copper or aluminium sheet
- Roofing felt
- Wooden structures with nails
- Aluminium roll-up doors
- Cutting ventilation openings in flat roofs and cladding structures
during fire-fighting missions to allow smoke, toxic gases and heat to
escape - this is an important supplement to forced ventilation.
- Searching for the seat of a fire, particularly in the case of
smoldering fires in the roofs of industrial buildings.
- Cutting access gaps in multiple wall structures.
- Cutting panes of glass.
The tremendous performance packed by the rescue saw STIHL 046 RHD is
mainly due to the following factors:
Performance factor Nr. 1:
The power unit
This impressive engine develops considerable power right from the
mid-speed range. That means sufficient feed force for the chain, with
reserves to overcome high cutting resistance.
Performance factor Nr. 2:
The cutting attachments.
These comprise the STIHL Rollomatic ES guide bar with the sprocket on
the bar nose.
The cutters on the STIHL Rapid Duro S chain are tungsten
carbide/cobalt tipped - one of the hardest metal alloys. And the
cutting depth limiter allows the bar nose penetration depth to be
adjusted from 0 - approximately 20cm.
Performance factor Nr. 3:
Top quality material is essential for rugged technology. An
impact-resistant electronic ignition system ensures easy starting and
smooth running of the engine, for example.
A heavy-duty filter system always delivers sufficient clean air, even
in very dusty conditions.

You can buy it off EBay.
Or make your own.
Aluminum powder and black rust.
Black rust FeO4 is formed when iron rusts underwater.
Brown rust FeO3 is formed when iron rusts in air.
You have to grind it up into very small particles.
You use to be able to buy alum powder in an old fashioned hardware
I didn't see any effective way in all these posts for ways to help you
to cut up the old ties, so let me offer this suggestion: go down to
your tool rental place and check out stump grinders. Our rental place
has a smaller one that rents for $25 or so a half day and munches
through old stump wood rather quickly. Although the chain is rather
wide, it isn't hurt by debris like a chain saw is. The machine is easy
to guide and control, and the only real downside is there will be a
whole lot of wood chips as a by product. Hope this will help.
