I doubt very seriously if you'll be able to find any replacement parts. Herein comes one of the fun parts of scale modeling - just make them yourself. It's not rocket science. If you've never scratch built anything, here's a great opportunity to do so, and it's not a particularly daunting task, either. The handrails can be constructed out of .015 brass wire, the stanchions can be cut from strips of polystyrene, and the chain is ready-made in various sizes/lengths - all available online or through your local hobby shop (if you're fortunate to have one close by). There are several tutorials on YouTube that can help guide you. All you'll need are a few tools for the miniature hobbyist - wire cutters, needle nose or thin, flat blade pliers for bending, and a pin vise with various little drill bits. Plus, the real satisfaction comes from knowing you built them yourself! Once you start, it opens up a whole new world for detailing and adding missing bits or pieces to your engines, rolling stock, or accessories. Just don't be afraid to try. You'll find it'll be well-worth your efforts in the long run.

A couple of weeks ago, I lucked into an estate sale that included a lot of different brands and gauges of engines, rolling stock, transformers, track, and more. There were a lot of things that were complete and operated just fine. There were many more that didn't and could use some TLC. One of the items I found buried at the bottom of a plastic tote was this locomotive. However, it's missing several parts that Bachmann no longer carries because of its age. I was wondering if there was anyone out there who could help, because I'm a masochist at heart and believe all old trains are worthy of care, and should be proudly displayed or run as they were intended, and I would like to get this engine running again. Here is a list of the parts that I need to complete the job:
Part 3701 - Pilot Truck and Wheel Assembly complete with Washer and Spring
Part 3702 - Trailing Truck and Wheel Assembly complete with Washer and Spring
Part 3704 - Draw Bar
Part 3705 - Draw Bar Mounting Block
Part 3710 - Screws (21 Pcs)
I know it's a shot in the dark, but if any of you have some spares, or know where I can find them, please let me know. Also, I could use the complete tender as it was completely missing. If you have the tender and/or the parts listed, please let me know your price(s) and how I may go about purchasing them. Thank you for your help!
