+  * **Guest Locomotive**
+ \\
+===== Definition =====
+A Guest Locomotive is an undefined loco object which could neither be found by **ID** nor by **Address** in the list.\\
+ \\
+===== Initiator =====
+The initiator is a Rocrail client and most likely Rocweb.\\
+If a client is capable to set a locomotive address by hand it could be that it is not defined in the Rocrail Model. (plan.xml)\\
+ \\
+===== The Guest =====
+In case of an undefined locomotive object Rocrail will generate one on the fly with the following settings:\\
+^ Attribute   ^ Value   ^
+| ID | guest address |
+| Address | guest address |
+| Protocol | NMRA DCC |
+| Speed steps | 128 | \\
+Long addressing is set if the guest address is above 127.\\
+ \\
+All other attributes are default values as defined in the **[[http://www.rocrail.net/doc/rocrail-wrappers/wrapper-en.html#lc|Loc Definition]]** wrapper.  \\
+The new locomotive object will not be saved at server shutdown, and is valid for the current session only.\\
+ \\
+===== Trace lines =====
+The Rocweb throttle, tries to use a Locomotive with address 33 which is not defined in the current layout:
