Movement of freight traffic movement of freight starts at the initial terminal where the train is made up in the classification yard. here cars are classified or sorted, those for the same destinations being collected in groups or blocks. these are assembled on a departure track. the number of cars assigned to a train is related as nearly as possible to the tonnage capacity of the locomotive. after assembling the various blocks of cars on the track from which the train is to leave, they are coupled up with air brake connections, then tested and inspected. defective cars are quickly repaired; if this requires more time than is available such cars are cut out and dispatched in a later train. the engine crew boards the train at the locomotive terminal. they pick up the caboose with the train and attach it to the rear end of the train, or a yard engine may handle the caboose. prior to leaving the yard terminal office the freight conductor receives a series of sheets called billing, which show the number, character and destinations of each car in his train, and checks the train for correct make-up or consist. when the train is ready to move, a signal from the conductor to the engineer starts it on its way. except for stops fore water or fuel a through freight train will run normally to the next intermediate terminal without stop or change in its consist. the conductor makes out what is called wheel report*3, listing the initials and numbers of each car, weight of the car, weight of lading and the points between which the train moves it. these wheel reports are the records from which the car accountant keeps trach of car movement and the statistical departament of the railroad compiles freight train and traffic statistics. at intermediate terminals cars consigned to destinations within the particular territory are cut of the train. new cars at intermediate terminals may be added. the train progresses by successive stops though other intermediate terminals to final destinations, where it moves to the terminal yard. at that point cars are classified for delivery to the various industries, the operation being carried out by local yard crew.

In my opinion, summer is the most beautiful time of the year, because it is very warm, everything is beautiful, and we have a great opportunity to relax. And summer is a time of holidays and vacations. We can go anywhere, have a wonderful time at the pond, in the shade of emerald green, splash in the warm water. And you can go to the mountains, ride a bike or play all sorts of games.

I want to share my impressions of the most memorable moment of the last summer vacation. In July, my family and I organized a trip to the forest for barbecue. A fire was kindled, meat prepared for roasting, and a tent pitched. While my parents were preparing dinner, I went into the woods to work up an appetite.

The forest that day was magnificent! The air smelled of flowers, honey, and strawberries. Everything was green, except for the trunks of the trees, which stood out in bright patches against the dark green background. Birds chirped in their own language, a woodpecker tapped. воть
