This item is best cataloged under its full name and BAC19509. The scale marker HO scale is part of the exact identity and should be matched before purchase. The year 1950 belongs to the listing identity; it should not automatically be treated as the manufacturing date of the item. The number 723046 separates this release from visually similar versions. That combination protects against accidental substitutions when related products share a subject, color, scale or series.
Confirmed facts versus assumptions
The product page identifies the item this way: “Bachmann models 55-Ton 2-Bay USRA Outside Braced Hopper - B & O (Capitol Dome) #723046 in HO scale.

The category-specific decision
The title of Bachmann HO 55-Ton 2-Bay USRA Outside Braced Hopper - B & O (Capitol Dome) #723046 may contain scale, road number, body type or decoder family, but no single phrase settles compatibility. Use BAC19509 with the images and current documentation. A visually similar car can carry a different road number; a similarly named decoder can use a different interface.
Test new rolling stock or electronics on a controlled section before regular service. That isolates clearance, pickup, coupler-height and programming issues without disrupting the full layout.
A closer project or collection check
For electronics, do not connect the item until the locomotive or accessory wiring is documented. For rolling stock, check free rolling, wheel gauge and coupler height. For structures, make a paper footprint before cutting scenery. Each approach tests the highest-risk compatibility point first.
The live page remains the source for current price and availability; the roster remains the source for what the layout already owns.
Why the exact photo set matters
Review all 3 available images in sequence rather than judging the item from the first thumbnail. Front, side, reverse, package and detail views answer different questions. The record is strongest when those views agree with the title and item number BAC19509.
Checks to complete before ordering
- Match the full title and BAC19509.
- Confirm the selected variant and displayed quantity.
