You are all so good at answering my questions, I now have another one! Is there any way to change the speed limit on track that has already been laid? For my mainline I used SRW1 Main which has a 50/30 limit. I'd like to change that somehow to 70/70. I know I can fix it for all new track but what about track already placed? What say y'all on this one??? Thanks! ! !

Use the select tool from the upper left flyout.
A flyout should appear in the right side of your screen. Here you can edit all values of the selected track.
