Railway lines are parallel
The question is baffling. They're not different. Perpendicular lines must be intersecting lines.The only lines that are not intersecting lines are parallel lines. If two lines arenot parallel, then they must intersect, and they can be perpendicular or not.
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.
Lines of latitude are horizontal and run parallel to the poles
They could be: parallel lines, perpendicular lines or intersecting lines
perpendicular line
lines that intersect= perpendicular lineslines that do not intersect= parallel
They are not. The perpendicular bisectors of a triangle, for example, intersect at the orthocentre of the triangle. So perpendicular lines can be intersecting and conversely.
On successful railways it has been found that parallel works the best.

No, because although perpendicular and intersecting lines do touch, parallel lines never meet.
No.
