See the resources in the header of the newsgroup, in particular the .tdl
layouts available at the train depot. Doodle your design in Track Designer
to see if it works first and you'll reduce your frustration.
Now to your particular question,
first, if you do the same diagonal shift on both sides of a loop, you'll
never get out of alignment.
Second, there are configurations that are very very close to working out.
One I (re?)discovered just the other day is useful in making dogbones that
end up with the standard 16 stud on center double track spacing...
Try this in Track Designer
go straight a while... then do one track piece LESS than 3/4 of a circle. Go
one straight. Now go 3 curves in the other direction. Now go straight. You
are 16 studs on center, or very very close, and your track ends are at the
same exact point as the track coming in, or very very close.
There are other ones too. In particular I found a folded dogbone config that
has 45 degree loops at both ends and one fold that worked out pretty close.
