I need some help.

[Triplex]

one of the factors that I dont like with this plan is if i keep it once around, even at a crawl it takes no time at all to get around.I also noticed the if turn a train in the reverse loop i have no way to re reverse it.

Is this correct for how the tracks connect?

I've arbitrarily designated one loop, in red, as the "main" route. The blue "alternate" route isn't a return loop.
That's what is taking up space while not increasing the length of continuous run.
