| 説明 | The amazing engineering feat known as the Zigzag Railway was completed in 1869. A zigzag was seen as the only way to progress trains down the Blue Mountains escarpment to the town of Lithgow. It cost £20,000 to £25,000 per mile to build the zigzag. Three gorges along the way were spanned by viaducts. Parts of the rock face are pierced with tunnels. The zigzag has a gradient of 1 in 42 and the fall from Clarence to the bottom of the zigzag is 210 metres (687 feet) over a length of 8,000 metres or 5 miles. The elevation of Clarence is 1,115 metres (3,658 feet) and at the bottom of the zigzag the elevation is 906 metres (2,971 feet). There are two reversing stations on the descent. Although one of the great engineer feats of Australia the zigzag railway impeded rail traffic to the west as it was slow and a cumbersome passage down the rock escarpment. It limited the size of the steam engines. In 1910 a new line was constructed, which is still known as the ten tunnel deviation, to bring the rail traffic down to the lower level. The Indian Pacific train still uses this route between Lithgow and Mt Victoria in the Blue Mountains. This new line was electrified in 1957. The zigzag lay forgotten until 1975 when it was restored for use as a tourist train. The narrow gauge steam engines used on the track come from Queensland. |
