The system proved its worth, was introduced by law on all lines in 1907 and is still the most important guideline in German railway traffic today.

If a train is travelling through a block section, the signal behind it must be set to &amp;#039;&amp;lt;nowiki/&amp;gt;&amp;#039;&amp;#039;&amp;#039;stop&amp;#039;&amp;lt;nowiki/&amp;gt;&amp;#039;&amp;#039;&amp;#039;.

As a result, most lines had many signal boxes only for operating the section signals, so-called &#039;&#039;block posts&#039;&#039;. Communication between these block posts and stations was necessary to ensure that there was really only one train in a block section at any one time. Initially, this took place via optical telegraphy or Morse code, but later via cable telephones. To avoid misunderstandings - with potentially fatal consequences - the &#039;&#039;train reporting procedure&#039;&#039; was introduced, which recognises standardised messages and wording for the most important operational events.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

It was only necessary to wait a few minutes after fast passenger trains, but a quarter to half of an hour after much slower freight trains. Not only was this regulation inefficient, but it also led to several railway accidents caused by inattentive railway staff or trains broken down on the track.

The system proved its worth, was introduced by law on all lines in 1907 and is still the most important guideline in German railway traffic today. It can be described as follows:&amp;lt;blockquote&amp;gt;Railway lines are divided into different &#039;&#039;block sections&#039;&#039; by signals. Only &#039;&#039;&#039;one train&#039;&#039;&#039; at a time is allowed in each block section. If a train is travelling through a block section, the signal behind it must be set to &#039;&amp;lt;nowiki/&amp;gt;&#039;&#039;&#039;stop&#039;&amp;lt;nowiki/&amp;gt;&#039;&#039;&#039;. It may only be switched back to &#039;&amp;lt;nowiki/&amp;gt;&#039;&#039;&#039;go&#039;&#039;&#039;&#039; when the train has left the block section and the following signal is set to &#039;stop&#039;.&amp;lt;/blockquote&amp;gt;This can be illustrated graphically as follows:&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Here, the first train travelled between Nuremberg and Fürth, reaching top speeds of up to 50 km/h. Despite initial scepticism, the new means of transport quickly spread throughout the country. In particular, the high efficiency of the railway, achieved through the low friction of the wheel-rail system used, surpassed any other means of transport known at the time and even exceeded the car to this day.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
