This item is best cataloged under its full name and BLR104. 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. That combination protects against accidental substitutions when related products share a subject, color, scale or series.
Reading the source record carefully
The live record provides the following product-specific information: “Blair Line 104 Highway Signs Construction 1950s-Present (black orange) HO Scale is the exact Blair Line item identified by manufacturer part number 104. The product photo is tied to this source record so you can confirm the package and intended use before ordering. How it fits the project Collectors and builders use this as a layout or rolling-stock item for a specific railroad scene. Check the manufacturer scale, dimensions, and package quantity against the build before opening it. Specifications Manufacturer: Blair Line Part number: 104 Shipping weight: 4 g Browse model trains and railroad supplies .” The wording is treated as a source excerpt, not as a substitute for independent fit, scale or condition checks.
What matters for this kind of product
The title of Blair Line 104 Highway Signs Construction 1950s-Present (black orange) HO Scale may contain scale, road number, body type or decoder family, but no single phrase settles compatibility. Use BLR104 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.
The details to verify next
Layout planning should include the item’s storage and handling path as well as operation. Long cars, tall structures and fragile details can fit the nominal scale but still conflict with curves, tunnels, platforms or storage trays.
Photograph the model from both sides and the underside when it enters the roster. Those images preserve reporting marks and hardware details for future comparison.
Image-by-image verification
1 product image were available to the catalog at verification. Use them as item-level evidence: zoom in on the SKU, graphics, edges, connectors, part arrangement or package callouts relevant to this model railroad accessory. Do not substitute a generic manufacturer image when the exact listing supplies a more specific view.

- Save the listing URL under BLR104.
- Compare the product image with the expected subject or component.
- Check whether optional tools, motors, paint, batteries or accessories are separate.

- Record any unanswered question before checkout.
