A typical semi truck will haul approximately 12,500 modular brick. A 50 ft. box car will typically haul 43,000 modular brick. This equates to approximately 48,000 lbs. on a truck and 150,000 lbs. on a 50 ft. rail car. If you are not shipping modular brick, determine the weight of the individual brick and divide this into the allowed weight of the carrier. Add a variant factor of 5% and this is the approximate weight. Contact the company freight department for actual number of a specific brick on a rail or truck.
