The advantage is that the locomotive can transport other trains while the wagons are being unloaded, for example. Technical problems on the locomotive can also be easier z. B. can be solved by using a replacement locomotive.<\/li>\n<li>Another method is to install the engine in the wagons to be transported &#8211; for example under the wagon floor &#8211; and thus provide propulsion (railcars). The advantage here is that you get more space for passengers since there is no longer a locomotive.

Steam engine<\/strong><\/p>\n<p>This type of drive was first developed in Great Britain at the beginning of the 19th century and laid the foundation for the rapid development of the railway.<\/p>\n<p>Steam is generated in a boiler and fed into the cylinders, which transmit their power to the drive wheels via a rod system. The boiler is usually heated with coal and has to be constantly refilled with water, as the steam escapes into the open after it has been used. For this reason, a special freight car &#8211; the tender &#8211; was usually coupled behind the locomotive, in which the coal and water supplies were housed.<\/p>\n<p>In the case of locomotives that did not need such large stocks, storage tanks for coal and water were attached directly to the locomotive (tank locomotives).<\/p>\n<p>At the beginning of the 20th century, it was discovered that the machines become significantly more efficient if the steam that has already been produced is heated even further to over 300 \u00b0 C. The so-called superheated steam locomotives were born, which gradually replaced the old wet steam locomotives.<\/p>\n<p>To operate a steam locomotive there were generally two people needed, besides the engine driver, the stoker, who had to shovel the coal from the tender into the boiler and who had to take care of the complex (fully analog) technology of the locomotive.<\/p>\n<p><strong>2. Diesel engines<\/strong><\/p>\n<p>With the invention and further development of the diesel engine, it also became interesting for the railways. An important point here was the development of high-performance transmissions, since a diesel engine, unlike a steam engine, cannot be started from a standstill under load. The diesel engine had the advantage that the locomotive only needed one person to operate it. Furthermore, the pollution of the environment from exhaust gases was significantly lower because the engine can simply be switched off when the vehicle is at a standstill.<\/p>\n<p><strong>3. Electric motors<\/strong><\/p>\n<p>In parallel to the diesel engine, the electric motor was continuously developed and then found its way into railway technology. The disadvantage of this drive, however, is the supply of electrical energy to the motor, which is why it is necessary to equip railway lines with a running power supply (to &#8220;electrify&#8221; them). Since this causes high investments, electrification only pays off if there is sufficient traffic on the railway line or special circumstances exist (e.g. subway).<\/p>\n<p>The electric drive is the most powerful drive in the railway, which among other things makes it possible to build and run high-speed trains. It is also better suited than the diesel drive for building railcars.<\/p>\n<p>If the electricity is generated in an environmentally friendly way, this drive is also the most ecological drive of the railroad.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1953\" class=\"elementor-tab-title\" data-tab=\"3\" role=\"button\" aria-controls=\"elementor-tab-content-1953\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">Axis formula<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1953\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"3\" role=\"region\" aria-labelledby=\"elementor-tab-title-1953\"><p>An essential way of describing locomotives is to specify the number and order of the axles.
