Railway Tracks

Railroad or railway tracks are used on railways, which, together with railroad switches, guide trains without navigation. They consist of two parallel steel rails, which are laid and fastened upon sleepers which are fixed in ballast to form the railroad track. Rail tracks are normally laid on a bed of coarse stone chippings known as ballast, which combines flexibility, some amount of elasticity, and good drainage; however, track can also be laid on or into concrete (across bridges, for example).

Salad

Salad is a light meal — or, as part of a larger meal, much more of an taster — consisting of mixed vegetables (usually including at least one leaf vegetable) or fruit, frequently with a dressing or sauce, occasionally nuts and sometimes with the addition of meat, fish or cheese. It is generally seen as a healthy dish, although not always low in calories, salt, sugar, or fat because of the dressing that is often added.The word "salad" comes from the French salade of the same meaning, which in twist is from the Latin salata, "salty", from sal, "salt".
