== Setting Up a Basic Razor Train ==
To create a Razortrain in Hammer, you will use a [[prop_dynamic]] to parent these models to an invisible [[func_tracktrain]] brush:
* <code>props_combine\combinetrain01a.mdl</code> (engine)
* <code>props_combine\combine_train02a.mdl</code> (full carriage)
* <code>props_combine\combine_train02b.mdl</code> (empty carriage)
Here is an example starting area:
[[Image:Trains1.png|400px]]
Next create a standard block with the <code>tools/invisible</code> texture, this will be our actual func_tanktrain entity. Now add a [[prop_dynamic]] using the model <code>props_combine\combinetrain01a.mdl</code>. Visible in the pic below is the razor train engine and the small block that we have made so far.
[[Image:Trains2.png|400px]]
Now, we are going to give the prop_dynamic model a name, <code>Train_1</code>. We are also going to set the parent to "RazorTrain" - we have not made the actual func_tanktrain entity yet but we will! We are also going to size the small block that we have made to be the shape of the engine and all of the cars (when we add them). Once you have finished that, select the box model and hit {{key|Ctrl|T}} and set the entity type to func_tanktrain.
[[Image:Trains3.png|400px]]
Now change the following items in the list:
*Name: RazorTrain
*Max Speed: 1000 (Or whatever you want)
*Initial Speed: 700 (Or whatever you want)
*Move Sound: ambient/machines/razor_train_wheels_loop1.wav (Or whatever you want)
*First Stop Target: path
You are also going to have to check the following flags as well: (I made a small change to the texture and size, just ignore that)
[[Image:Trains6.png|400px]]
Next we are going to make our [[path_track]]s so go ahead and make one now. Position it right on top of the tracks and name it <code>path</code>. Then all you have to do after that is hold {{key|Shift}} and move it along the tracks - this will automatically create and link additionally path_tracks.
Next create a [[ambient_generic]] with the sound of the razor train horn and set it up to be triggered somehow. As in one of the path_tracks tell it to play the razor train sound on pass. (See Pic)
[[Image:Trains4.png|400px]]
Now all you have to do now is tell each path_track to go the speed you want and you are done. To add more cars, you can hold shift on your original prop_dynamic model and drag it to the position you want. Now all that is left is to change the name, leave it parented to the func_tanktrain entity, change the model and resize the block to fit the train.
[[Image:Trains5.png|400px]]
Now don't forget to add a player spawn and test out the map. You will also have to add a logic_auto with the following items:
{| class=standard-table
! || Output named || Target entities || Via this input || Parameter || Delay
|-
|[[Image:Io11.png]] || OnMapSpawn || RazorTrain || StartForward ||  || 0.00
|}
Our finished product:

== Notes ==
* If you want a prop to behave as a train, parent it to an invisible {{ent|func_tracktrain|}}.
* Trains must be constructed facing east (in the Top viewport of Hammer, this is facing right). They will automatically align to the path in-game. If the train is not constructed facing east, it will not face the correct direction in-game.
* You don't need to create each {{ent|path_track}} by hand. Create the first one, then <code>Shift-drag</code> it to create another; the new one will be automatically linked from the previous one. This works even for inserting new {{ents|path_track|s}} between existing ones.
* For Team Fortress 2 mappers: If you wish to duplicate the trains as seen in CP Well, it is necessary to parent a [[trigger_hurt]] to a func_tracktrain, as trains will not normally hurt on touch. To get the "killed by train" icon in the killbar, the damage type must be set to 'Train'.
