Zig zags suffer from a number of possible limitations:
The length of a train may be limited by length of track at the top and bottom points.
Reversing a train without running an engine around to the rear of the train is hazardous.
The process is slow.
On the other hand, zig zags may be a quick and cheap alternative to expensive and slow to build tunnels.

The ZigZagRailway is a heritage railway at Lithgow in New South Wales, Australia on the site of the famous Great or Lithgow ZigZag which operated between 1870 and 1910.
The original Bottom Road of the ZigZag is mostly still in use as the current main line, with the present locomotive depot located on what used to be the connexion between the Bottom Road and the ZigZag.
ZigZag services start from the Bottom Points at an altitude of 993 metres, originally the first switchback, and proceed uphill along Middle Road, through a short tunnel and over two viaducts to the Top Points, originally the second switchback.
One of the odd features of the ZigZagRailway is that although it was originally standard gauge, as the main line is now, it has been rebuilt as a narrow (3 feet 6 inches) gauge line, since available rolling stock was of that gauge.
