    Including electronic sensors that will trigger a full break of the train if a gap is detected on the train's path 10 km ahead of the path of travel.
    I was not referring to the Metro. I was referring to the potential for inter-city railway systems. You underestimate your countrymen's abilities to work with.

    Nothing to improve the north coast, I expect.

    You do understand the difference between iron and high strength steel rails? Right???
    The cutting wheels will be more costly than all the steel they get to cut away...

    It's like cutting the butter knife with the butter stick itself...
    One Dominican at a time please!

    That will be on the second phase of that hybrid rail system.

    Cuba will have them first. Oh, I forgot, Cuba has had them for 60 years.

    Couldn't resist . . .

    The Cuban rail system is not in good shape by any means, but there are several trains daily that cross the ENTIRE country from Havana to Santiago, stopping at many cities.

    And I can hear it already, "it's unreliable", "it's falling apart", "it's antiquated", bla, bla, bla . . .

    Sure, it's all those things and worse, but let's see how long it actually takes to be able to board a train in Santo Domingo and travel directly to Puerto Plata.

    Takes about 90 seconds with the correct tool.

    No access to power because the power company turned of the electricity? After all, this is the DR. Use a torch and cut through in less than 3 minutes with Oxy Propane:

    Perhaps you prefer oxy acetylene?

    You do realize that the materials cost to perform those actions in the DR far outranks the profits per linar foot cut away? Like I said in my post!

    The other thing is that those rails you see getting cut, are not the ones in use nowadays in hybrid rail systems.
    The contact surfaces of the rails are not plain steel anylonger. You need a very expensive type of blade to cut it and it's only done by means of torch or plasma at a very high degree of heat unlike before.

    If they used regular steel rails on hybrid systems, the wear and heat problems would make them impossible to upkeep.
    These alloys are far tougher to cut by conventional means as you posted examples of.

    It just ain't gonna happen. Period.

    The rails cut in the videos I show are not "ordinary" steel. They are the steel used to make rails.


    What is the exact alloy used in these magical new rails, likely used only in the DR, and only able to be cut with alien technology and what is the Brindle hardness number of these rails?
    Harder than 400 HB?
