+ | ===== Introduction ===== | ||
+ | The words driving direction, forwards and reverse are very blurred and therefore sometimes lead to confusion. They are only precise if it is clear whether they refer to a train or to the locomotive only. | ||
+ | |||

+ | \\ | ||
+ | |||
+ | For this the easiest way of understanding is to consider a freight train with many cars for example, pulled by an electric engine with the two cabs of the locomotive marked with 1 and 2. | ||
+ | The modeler is aware that such a locomotive moves forwards when its cab 1 is at the front end seen in driving direction (with three-rail engines | ||
+ | | {{pickup-shoe.jpg}} | ||
+ | | A Märklin electric locomotive facing left which is only obvious \\ from the position of the slider (pick-up shoe) | | ||
+ | \\ | ||
+ | |||
+ | If such a train, however, is seen driving in the real world from afar, it will always be clear that the train is moving forwards although it may be unknown which cab is at the front end. This is exactly what the direction of travel of block side routes refers to: It's about the direction of movement of the entire train (where the train can be a single locomotive, too). | ||
+ | |||
+ | The consideration here is a long freight train will never go reverse but always forwards with the locomotive pulling at the front end. Therefore, the direction of movement with block side routes is strictly forwards: If a route is defined from A to B, then this is " | ||
+ | |||
+ | The directions of railway lines are sometimes addressed by the terms " | ||
+ | |||
+ | With block side routes the moving direction of the train (up / down) is set by the block enter side: Depending on at which side the train enters a block it either moves up or down through the block and possibly the following route. The arrow shown in the block symbol is indicating the direction of movement of the train by pointing to the exit side of the block. | ||
+ | |||
+ | The relation between the __orientation__ of the locomotive, i.e. where cab 1 and 2 are located, and the desired direction of the train is represented by the __block direction arrow__ in Rocrail.\\ Metaphorically speaking: On model railways it is crucial in which orientation the locomotive was __placed__ on the tracks, e.g., by hand. | ||
+ | |||
+ | Technically speaking, the direction arrow indicates in which way a speed command is to be interpreted: | ||
+ | |||
+ | For [[http:// | ||
+ | |||
+ | In order to understand the meaning of the __swapped__ regarding commuter trains one could consider, for example, a push-pull train with the locomotive at one end and a control car at the other end. If an engineer is on the locomotive driving the train (forwards as the train is behind him) to a terminal station where the train has to stop, then the engineer needs to change (swap) his __place__ in order to drive the train in opposite direction: He has to leave the locomotive and to go all the way to the other end of the train and take his seat on the control car. Now he can take the train back the other way, of course in forwards direction because the train is yet again behind him. | ||

+ | ===== Avoiding problems with unwanted direction of travel ===== | ||
+ | To ensure that a train (or a locomotive) drives in the desired direction in automatic mode and routes are set by the automatic in exactly the same direction, the following points should be observed before starting the locomotive. | ||
+ | |||
+ | Assuming that Rocrail has been started, track power is switched on and the train is in the considered block: | ||
+ | |||
+ | - Determine in which direction the train should start from the block. {{ : | ||
+ | - Make sure there is a valid route to the next block in that direction. | ||
+ | - Select the loco in the loco control panel (click on the loco ID). | ||
+ | - Make sure the direction is set to **> >** in the throttle of the loco control panel. (See picture on the right) | ||
+ | - Let the locomotive drive a little bit with the help of the throttle and stop again. | ||
+ | - Is this the desired direction in which the train should move? | ||
+ | * If yes, continue to the point 7. | ||
+ | * If not, select the locomotive' | ||
+ | - Does the arrowhead in the block symbol point in the desired direction? | ||
+ | * If not, select the locomotive' | ||
+ | |||
+ | > **Note:** From point 3 on, the sequence shown must be observed and adhered to! | ||
