n scale trailer-on-flatcar history
  • The decks, flat cars and trailer kits do not include pins or hitches. This enables the customer to use any method desired.
  • Pins UNS Method 1: Drill a 5/64 inch hole (see part A-840) about 3/16 inch from the front of the trailer. Glue a 1/16 inch rod (part A-839) into the hole to stick out about 1/8 inch.
  • Pins UNS Method 2: Purchase part A-826 and glue these pins onto the trailer. The hitches will accept these pins to secure the trailer onto the car.
  • Type A hitches (part A-831) were produced starting in 1956. Type 2 hitches (part A-832) were produced starting in 1961.
  • Hitches are added to the cars to take 1, 2 or 3 trailers depending on the length of the car and the trailers.
  • Hitches can be attached with glue or with two-sided tape.
  • Prior to the production of hitches, trailers were tied down. Some railroads used frames (part A-820) to attach the front of the cars to the deck.
