I did find out that the postwar engine I was going to covert has large wheel flanges that hit the ties on this code 148 rail. Gargraves 2 rail would work fine. I'll test it at a later date. It won't look perfectly scale but would be much nicer. The sliding shoes will be the challenge. Fortunately, they'll work on conventional 3 rail track too.
The water got within 6" of our house last night but the break in the rain has allowed it to drain off so the street is passable again. We are in Clear Lake near NASA so we are near the bay where it drains. The situation throughout the city is mind boggling.
