This is an HO Scale DECAL set. There is no models or prototype equipment in this listing.
This set is for Norfolk and Western's vast fleet of black NW painted diesels. This set includes 42" heralds for road diesels, 24" heralds for smaller switchers and slugs, and 12" nose heralds. Stripes are also included to go under the unit number of locomotives equipped with swivel butt couplers. Set has been upgraded to include data and numberboards. Each set will letter several locomotives.
Locomotives with swivel butt couplers have no coupler alignment control and are prone to derailments when the couplers buckle between diesels during pushing moves. These locomotives were not allowed to be coupled together unless a locomotive with alignment control was placed between them.
