In the Works: Building a Burlington Northern EMD SW1500 in HO Scale Part One

        In January of 1973 the Burlington Northern received their only order from Electro-Motive Division (EMD) of the SW1500. All other groups of the SW1500 on the Burlington Northern roster came from its predecessor, Great Northern (GN) and later in 1980 from the Saint Louis and San Francisco (SLSF). The January EMD order (order number 71605) saw fifteen new switchers numbered from 310-324. For this project I have selected road number 320 because I have come across a photo of it in Whitefish, Montana during the 1980’s which is the era and region I model most of my BN equipment, so a win-win for me on this one. A photo of this locomotive can be found on railpictures.net. 

Most of the parts need are here along with the Undec locomotive  
          I started with an undecorated Athearn “blue box” kit it was bought it off of a friend of mine along with a few detail parts. The model came with a DCC decoder that was partially finished, only the motor and truck leads were attached. This will be changed to a DH165 from Digitrax but that is for a later paragraph and part. First items to replace were the truck side frames for the proper style for this particular locomotive. The model came with Flexicoil trucks side frames and with this EMD order the Burlington Northern opted for the AAR-B trucks, like many of their other switcher series models. The kit used is from Smokey Valley and each side frame consists of one frame, two bearing caps, and the air brake cylinder. As I go along with this project these will receive some attention with extra details, including a speed recorder, airlines, and sanding lines with these details, the trucks will really look the part underneath this locomotive.


          The detailing of the shell starts with the front of the locomotive. The original coupler buffer plate and MU hose holders were remove and replaced with a proper Detail West buffer coupler plate and 17” straight grab irons to hold back the MU cables. Next, the MU hoses were installed. I went with the now discontinued Overland brass MU cables. I like the look and the strength theses brass parts have, I plan on using them on future projects until I run out of them. It has been awhile since I have worked on any major HO scale projects of this caliber, with that said, I decided to try out a Cannon and Company safety tread kit for this locomotive. In continuing with the detailing the front of the locomotive, the solid steps originally on the shell were cut off and replaced with see through ones from the Cannon and Company kit. With a pleasant surprise, I was able to install them without any major issues.




         Lastly for this first part, the coupler cut lever was installed with the plastic brackets from Details Associates. The holes were drilled in and the brackets were carefully pushed through the cut lever bar and slide into place, once all four were slid though the holes on the pilot of the shell received a dab of plastic model glue and given a chance to become slightly tacky. Once tacky the cut lever bar was carefully set into place and allowed time to dry before it was handed to install the air hose on the front of the model by simply drilling a hole and attaching it with CA glue. Before, I completed the front of the model I installed the beginning of the safety tread piece with CA glue. There are still some small details to install on the front before I can call it finished but it will be saved for the next part of this series, stay tuned for the next part where I tackle the long hood and air tanks on the SW1500. Happy modelling! TRWBM
