Training - signs

At Stewart Park, there is a train engine for kids to play on, right near the clamshell, the ballfield and the golf course. Rarely ever have i seen many kids playing in the variety of compartments and infolds that old engines have - but the sign says it all - liability is more costly. So trains disappear as a way of life and trucks, three long and over-heavy barrel down the freeways intermixed with passenger traffic. Wouldn't it make sense to invest in a public works project to rebuild the rail system and at the very least, efficiently ship goods via the network. Passengers would take that much more enthusiasm because cargo doesn't complain. Given the high speed rail variety available in some other places - i think this gothic is best left as a relic in a park for kids to play on, even at their own risk.
