You can easily add grab irons with a separate detail kit. And it has correct RP - 25 metal wheels and Proto MAX magnetic couplers. Note: When using in DC mode, don't use power packs over 18V, like MRC 1300 - series ones due to decoder issues.

Using this Walthers HO Scale EMD SD75I locomotive is a breeze. If you're using it on a DCC - powered layout, just connect it to your DCC system and start operating. For DC - powered layouts, make sure to use a power pack that doesn't exceed 18V. The MRC 1300 - series power packs are not recommended because they can cause issues with the decoder. When running your locomotive, you can change the air horns and bells using the CV settings. This gives you different sounds to add variety to your railroad experience. As for maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body, wheels, and gears. Check the wheels regularly for any debris that might affect its movement. If you want to add grab irons, you can use the SD70 - Series Diesel Detail Kit (910 - 261, sold separately) and follow the instructions on the kit. Store the locomotive in a dry place to prevent any damage. With proper use and maintenance, this locomotive will provide you with many hours of fun on your HO railroad.
