Assuming two pairs of railway lines join together via points, to become
one line on a narrow gauge railway, the line you are on, then a line to
the left- you are progressing from the the line on the right, onto the
single pair of lines.

Points are set for the line on the left, rather than you line. Is is
normal to just drive the engine through the wrongly set points?
