Bachmann N Scale KCS #286476 Center-Flow Hopper: Item 17556 Guide
The Bachmann N Scale ACF 56-foot 4-Bay Center-Flow Hopper, Kansas City Southern #286476 (item 17556) is a covered hopper for N scale freight trains. Bachmann’s official item page lists it at 1:160 scale and gives the model measurements as 4.5 inches long, 0.8 inches wide, and 1.2 inches high. The item number is 17556 and the UPC is 022899175560. The manufacturer also specifies a separately applied roofwalk and brake wheel, magnetically operated body-mounted E-Z Mate Mark II couplers, and blackened metal wheels with RP25 contours.
Match the KCS release
Confirm the railroad, road number, and manufacturer item number together. This version is Kansas City Southern #286476, Bachmann item 17556, and Muncle Mikes item number BAC17556. Similar four-bay hoppers are offered with different markings and may have different sizes or operating details, so verify the exact N scale photograph and not just the family name.

Bachmann describes the four-bay Center-Flow prototype as a design developed by American Car & Foundry in the mid-1960s for granular materials such as plastic pellets and animal feed. The four outlets below the body support rapid unloading at compatible facilities. These are general prototype details, not evidence that road number 286476 served a particular industry or carried a specific commodity.
Plan an N scale bulk-freight movement
The covered body and compact N scale dimensions make this hopper easy to place within a small-layout freight plan. Bachmann lists the model at 4.5 inches long, but remember to include coupler spacing when estimating siding capacity and switching room. The 1.2-inch height and 0.8-inch width help check tunnel, bridge, and adjacent-track clearances. If an unloading structure or scenery is close to the track, test the full route rather than measuring only a straight section.
A covered hopper is suited to bulk materials protected from weather. On a layout, the car can suggest a movement from a supplier to a processor or an industrial customer with compatible unloading equipment. The product page does not say a model cargo load is included, so confirm package details before creating a loaded scene. A separate load should fit the body and remain secure over curves without fouling the roofwalk, couplers, or nearby structures.
Features and operating compatibility
The item-specific features from Bachmann include a separately applied roofwalk and brake wheel, body-mounted magnetic E-Z Mate Mark II couplers, detailed trucks with see-through sideframes, blackened metal RP25 wheels, and added weight for tracking. Body-mounted couplers can influence how a car moves through tight curves, so test the model on the smallest-radius track in your operating plan. Check the coupler height and magnetic uncoupling method against the rest of the fleet.
The added weight is intended to support tracking, but it does not replace sound trackwork and careful setup. Inspect wheel alignment and couplers when the car enters service. If using a mixed-brand N scale fleet, confirm that the car couples and rolls reliably with the neighboring equipment rather than assuming every N scale standard will behave identically.
Kansas City Southern roster and historical accuracy
The KCS markings make #286476 useful for a Kansas City Southern roster or a mixed train where the railroad identity fits the route. Bachmann’s source confirms the road name, number, and item, but does not document the service history of this particular car. If modeling a specific year, route, or customer, consult dated photographs or railroad records. The general development date of the Center-Flow design does not establish when an individual numbered car was active.
Before adding item 17556
- Confirm Kansas City Southern #286476 and Bachmann item 17556.
- Match N scale, 1:160, to the rest of the train and track.
- Check the 4.5 × 0.8 × 1.2-inch measurements against sidings and clearances.
- Verify body-mounted E-Z Mate Mark II coupler compatibility and curve performance.
- Plan unloading scenery around the four-bay prototype design without assuming a model load is included.
- Use historical sources for claims about the specific road number’s service.
These checks connect the published measurements and operating features to practical layout use while keeping commodity examples and individual car history appropriately scoped.

Keep an N scale operating record
When the model joins a fleet, note the item number, road name, road number, and coupler type in the roster. A quick photograph of the roofwalk, discharge bays, and reporting marks can help distinguish it from another four-bay car later. Record any load as a separate accessory if you add one. This makes it easier to plan compatible equipment and prevents prototype cargo examples from being mistaken for the contents of the Bachmann package.
For regular operation, test the car in both directions through the route and watch for interference at turnouts or tight curves. The product measurements provide a starting point for layout planning, but a physical test checks the actual track geometry and neighboring scenery. If clearances are close, verify with the car itself before building around the assumed dimension.
