3DC to Railworks - Locomotive: Detailing Part 2

153. Build the exhaust stack by Chamfering a cube, then layering other shapes with it. You may delete some faces and use the Double-Side plug-in as well.

154. The ditch lights and MU receptacles are all basic cubes and cylinders.

155. The windows for the cab, which will have TrainGlass effects applied later, are simple planes with the Double-Side plug ran on them. You can make planes either by deleting all of the faces save one from a cube, or select a cube face ("3", click) and duplicating it.

156. Windshield wipers start out as basic cube shapes resized to fit, then divided, pushed, and pulled.

157. After they are placed on the window surface, another cube is added to them, shaped, and positioned for the actuator.

158. In order to provide animation for these, we need to change the pivot point on the wiper arm to the end. Do this by selecting the end face of the wiper arm and running the "Shift Centre on Selection" plug on it. This may change the wiper's position, but you can move it back into place.

159. Duplicate the wipers to the other windows. Animations move the Group, not the individual part, so these parts should be grouped as shown, outside of the main Engine groupings.

160. The sand and toilet water hatches are made from two resized cylinders - one for the main pipe and one for the lid. Details such as hinges will be drawn on later. The grab irons on the nose are made the same way as the ones on the back of the locomotive are made - Piper and Extrude.

161. The "lit" aspect lenses for our number board and lights are made by selecting the face of the light and duplicating it about 1/2 and inch (.05) in front of the "unlit" lens. Please keep in mind that these new parts will be in a special Grouping later on that will allow them to be turned on with the flick of a switch in the locomotive cab.

162. Do a little underside piping using a cylinder shaped to fit and the Piper and Extrude commands (we should be getting good at this by now).

163. Creating the interior of the cab for the locomotive requires measurements and/or photos of the cab. These shapes that we create for this model will be low resolution and have textures in place of actual controls, but these shapes will also be used and detailed later for the model of our 3D Cab.

For this model of a C39-8, I refer to photos from the Internet to begin cubing and shaping the basic control panels.

164. Here we rotate the control stand 45 degrees, then angle the stand that holds the brake controls another 30 degrees.

165. Drag the edges of the main control stand to match the side of the brake stand, so it will look as if they are one piece

166. We place another shape that will comprise the bottom of the radio box. Not shown is the radio box itself, which was added later.

167 Place the rudimentary control stand into position inside the cab. Remember, we don't need to detail it with parts, just texture it to look like a control stand. This will only be seen from outside the cab.

168. Now using cubes, a little Extrusion, and a lot of Chamfering, we make seats for the Captain and his mates.

169. Copy your chairs over to the other side of the cab, and make sure you have the final placement of all the furnishings in the cab. You will be using these items in your 3D cab, and you don't want obvious movement of the furnishings when you switch from outside mode to inside mode and vice-versa.

170. The Locotrol antennas are simple cylinders, shaped to size and placed one on top of the other.

171. The Handbrake wheel is also two cylinders. The wheel itself is a solid shape, and the spokes will be Alpha-painted on later.

172. Sun visor is a solid cube, shaped to fit, with the bottom, side, and back faces deleted, then canted and put into place.

173. Put a couple of cube shapes on either sides of the window to simulate mirrors, and on the top and bottom of the sun visor to simulate a slide track.

174. Horns are another one of those shapes that you have to feel to get it right, and it may take several tries to do so. They are also a very high-poly object. Start with a cylinder, resize it to the rough shape of the bell, then run the Taper plug on it.

175. Extrude the top face of what is now our bell, then select all sides ("3", CTRL, click or drag), and use the Duplicate function to copy the side we just selected.

176. Delete the faces we previously selected, run the Taper operation on the new part, and move it down onto the bell.

177. Extrude the top face again and taper just a little more.

178. Place a cylinder, shaped to size, on the narrow end of the horn to simulate the actuator.

179. Turn the horn over on it's side, delete the interior faces, and run the Double-Side plug-in on it.

180. You can join all the parts of the horn together, copy it, then resize it to make different sized bells for different tonal qualities. Here, a simple cube has been Chamfered and shaped to form the framework for the finished horn.
