Athearn Ready to Roll HO Rio Grande, D&RGW, DRGW, SD50, Unit #5511 NIB. I am selling my whole fleet of Rio Grande SD50's now. These are all hard to find in one place, but here they are. This auction is for #5511 only. See my other auctions for all other produced engine numbers.All of these units in the SD50-series listings this week are either mint or new with test running. They have been shelved since I purchased them and the boxes have shelf wear. Shipping is via USPS Priority Mail to the 50 UNITED STATES and USPS Priority Mail to International destinations. Combined Shipping is offered for multiple purchases in the same week. I typically ship on 2 weekdays each week. I accept PayPal as the only method of payment. Thank you for looking.
