inexpensive railroad ties

Improving our transportation infrastructure can be really expensive, it can cost million of dollar, but since we are in a high tech generation, we can make some alternative and one of them are the composite railroad ties, and maybe you wonder what made of this railroad ties. This made of recycled plastic (good) which can be last up to 75 years which are longer than regular ties which last only for 15 years or so, and they don´t have the harmful chemical used to make the wooden ties last longer. I think this new technology is very helpful for every one of us.
