Bachmann 18713 HO Pennsylvania #226136 Hopper: Yellow Ball Guide
Bachmann item 18713 is an HO scale Bethlehem Steel 100-ton three-bay hopper decorated for Pennsylvania #226136 in the Yellow Ball scheme. The road number is the quickest way to distinguish it from another Pennsylvania Yellow Ball hopper in Bachmann’s catalog, #227291. This guide records the exact identifiers and measurements for #226136, explains what the listed load and empty-car parts are for, and gives a practical setup check for an HO layout.
Identify #226136 before comparing listings
- Manufacturer: Bachmann
- Item number: 18713
- UPC: 022899187136
- Scale: HO, 1:87
- Railroad and road number: Pennsylvania #226136
- Scheme: Yellow Ball
- Car type: Bethlehem Steel 100-ton three-bay hopper
- Model dimensions: 7 in. long × 1.5 in. wide × 1.8 in. high
Bachmann’s hopper category also lists a Pennsylvania Yellow Ball model numbered #227291. The shared railroad and scheme make the number especially important: a page or collection tile that says only “Pennsylvania Yellow Ball” may describe either car. Confirm #226136 in the title or exact product images, then use item 18713 and UPC 022899187136 to anchor the record. Do not substitute the neighboring road number just because the paint scheme and body type look similar.
When cataloging a model already in hand, save a clear side photo of the lettering and a photo of the package label. Keep road number, item number, UPC, and scale in separate fields. That makes it easier to detect a mismatch if a future marketplace or retailer shortens the title.
Understand the loaded and empty presentations
Bachmann lists a removable coal or stone load with item 18713. It also lists interior wall braces for a realistic empty-car appearance and notes that assembly is required. Optional modeler-installed weights are listed as included and assembly-required as well. Those parts allow different display choices, but the manufacturer page does not identify a particular commodity or operating history for car #226136.
Before assembly, review the current instructions and sort the supplied parts. Choose whether the car will be displayed with the load or as an empty hopper, then fit the applicable components as directed. Store the unused removable part safely. If you install a custom load or alter the supplied setup, note the change in your roster so later photographs are not mistaken for the factory configuration.
Use the listed measurements to plan the route
The exact product page gives the model dimensions as 7 inches long, 1.5 inches wide, and 1.8 inches high. Use these values to check storage, close structures, bridge openings, tunnel portals, platforms, and parallel-track clearance. They describe the model envelope; they do not provide a minimum curve radius. Bachmann’s page reviewed for item 18713 does not publish one.
Test the car slowly through the tightest curve, turnout, and grade transition on the intended route. Watch the trucks, wheels, and couplers, and look for contact with scenery or neighboring cars. If the model runs close to a structure, test the actual spot rather than relying on an assumed HO clearance. A successful test documents your specific layout and equipment; it is not a universal compatibility guarantee.
Check the separately applied details
Bachmann lists air tanks, a brake valve, a brake wheel, and bracing among the separately applied details, along with a detailed chassis and underbody. Inspect the parts before handling and again after assembly. For a used car, close photographs of the underside and ends can reveal missing details that a broad side view may hide.
The listing also specifies magnetically operated E-Z Mate Mark II couplers, detailed trucks with see-through sideframes, and blackened metal wheels with RP25 contours. Check coupler height and secure engagement with the locomotive and cars in your consist. Mixed-brand equipment may need adjustments even when all pieces are HO. Test the actual connections through curves and turnouts before running a longer train.
Place the model in a period scene carefully
Bachmann says the Bethlehem Steel 100-ton three-bay hopper type first appeared in the 1960s and describes greater capacity than earlier forms. Its line includes schemes representing different operators and periods. That gives a broad modeling context, but the product page does not supply a full service history for Pennsylvania #226136. For a layout set in a particular year, verify the prototype’s individual history before treating the model number as proof of a precise date or route.
The Yellow Ball name is a useful catalog distinction for this model, while the road number remains the stronger release check. Use the product-specific listing for the manufacturer’s model identity; keep prototype research and the model’s visible decoration as separate kinds of evidence.
Keep a clear roster entry
A concise record is “Bachmann 18713 — Pennsylvania #226136 — Yellow Ball — HO 1:87 — UPC 022899187136.” Add whether the removable load is installed, whether the empty-car braces were assembled, and whether the optional weights were fitted. Record condition and modifications separately from the manufacturer’s description.
For a pre-owned example, ask for photos of both sides, the interior, underside, trucks, couplers, load, braces, and package label. Check that the visible number is #226136, not #227291, and confirm which loose parts are included. The current store listing is the place to check today’s price and availability.
