Wow machines like that train are in museum's in the west incredible testament to when things were built to last back in the day.I worked in the track dept for a high speed railroad! Used heavy equipment to build track! Lol this is amazing to see!If it does no break dont fix it .Best lesson about starting small but dreaming big.Unbelievable, no inert government forced ways. The way of the people without lots of government intervention. Some places should take notice
