No they aren’t. They are made of CONCRETE instead of creosote coated WOOD. They are a bit easier to manufacture, don’t wear as easily, last a while, and hold track in place better. Amtrak uses them on the NEC and is starting to install them on the Keystone between Philly and Harrisburg...
Sorry, too much chianti. I meant rails not ties.
