Note: EMD delivered the DRGW SD50s to the Rio Grande pretty much just as you see them in the model of 5507 above.. no gyralites, and a differently arranged 5-chime horn cluster with all bells forward - just like what Athearn supplied! However, before they entered service, Mid-America Car Co of Kansas City was contracted to install the DRGW-specific appliances such as the nose-mounted gyralite, reconfigured five-chime airhorn cluster and whatnot.
I also added the following:
Details West #206 snowplow
Notched out the anticlimber on both ends to add a:
Details West #249 MU junction box with hose
Detail Associates #2212 Coupler Lift Bars
and more MU hoses yet to come..
