hi i need to produce a 300 word report on the construction of structures aligned to the railway infrastructure and explaine the impact of track engineering construction. and my report should include examples from the following tunnels, side bridges, sea defences, platforms, operatinal bulidings, platform awnings, mast and towers. iv started to answer the report but im not to sure if iv stuck to rigth path of the question. so i wounder if any one called help me. Solution Railway is like a lifeline to a country. Most.of the people and goods are transported through railways. As railway runs mostly on land , in order to make it accessible to most part of the land supporting structures are made. Some of them are discussed below. Tunnels- These structures are mainly made when the terrain are rough or they are at very high altitude. At very high altitude it becomes difficult to travel and if travelling is done it is done at very low speed. It is basically carried out in hilly areas. So to overcome this problem tunnels are being constructed in the hills. This solve 2 main purposes. Firstly it reduces the travel time and secondly it connects the places. Side bridges- They are mainly constructed in order to connect the places divided by a water , valley etc. Sea Defences- They are mostly constructed along the sea shore. When a railway passes through sea , it is very likely that it will get affected by its tides. In order to neutralize it sea defences are made to avoid water coming on the tracks and also to avoid soil erosion beneath the tracks. Platform Awnings- Thes structures are mainly above the platforms. These are basically shed type of structures. They can solve many purposes. Firstly they provide shed and shelter to people beneath. Then they lower the temperature from around 5-8 . Installation of solar panels above them can lead to generation of electricity. Platforms- They serve the purpose of people boarding in and out of train. They also act as waiting area for passengers. They are designed according to train length and height. A busy station has more no of platform compared to less busy one as more no of persons are arriving and departing at a busy station compared to less busy one. Mast- They are constructed to hold the electric cables. These cables provide electricity for the train to run. Towers- They are constructed basically for signaling system..
