Until the starting 1960s, vehicles that were moved by railway were taken in boxcars.
 These were 50 feet lengthy with double-wide gateways. Within were space for four full-sized vehicles on a two-tier owner - two raised up off the floor on a steel owner and two others located in below them.
This properly secured the vehicles during transport but was not very efficient has the body weight of four vehicles been far less than the biggest possible body weight a boxcar that sizing could carry.
 When 85-foot and 89-foot flatcars came into support, it was possible to program a finish of 15 vehicles in one car on tri-level automated racks. But it still did not exceed the biggest possible allowed body weight for each flatcar. 04 more images after the break...
When Chevrolet started creating ‘Vega’ during the Seventies, one of the priority objectives was to keep the price of the car down around $2,000 in circa-1970 cash. At enough time, the delivery price for going a loaded train car from the Lords town set up plant to the Traditional coast - the lengthiest variety that vehicles designed at Lords town would need to trip - was around $4,800. Since the Vega was a subcompact, it was possible to media three more vehicles on a train car for a finish of 18, instead of the frequent 15. But that still worked out to around $300 per car – an important price for a $2000 car. If only Chevrolet could get more the state of lass Vegas on a train car, the price per system of moving them would go down.
The experts at GM and the South east Traditional Railroad came up with an amazing solution. Instead of operating the vehicles smooth in a trench, the the state of lass Vegas will be placed top to base on a specifically designed auto-rack – the Vet-A-Pac. Within the same variety of an 89-foot car, the Vet-A-Pac could keep as many as 30 vehicles instead of 18.
Chevrolet's purpose was to offer The state of lass Vegas cause with fluids and ready to produce to the car automated supplier. To be able to be able to trip nose-down without leaking fluids all over the train, Vega experts had to design a exclusive engine oil baffle to prevent oil from arriving into the No. 1 syndical tube, battery energy pack had gel caps located great up on the returning benefits of the situation to prevent level of acidity losing, the carburetor circulation bowl had a exclusive tube that eliminated petrol into the vapor tube during delivery, and the windows device program was status at a 45 stage place. Unpleasant spacers were wedged in beside the powertrain to prevent damage to engine and transferring sets up. The throwing sand throwing sand wedges were removed when vehicles were unloaded.
The Vega was significantly well-known when it was provided in 1970 however it quickly obtained a reputation for unreliability, corrosion, issues of security and terrible engine durability. When the Vega was ceased, the Vet-A-Pac vehicles had to be obsolete as they were too particular to be used with anything else. The Vert-A-Pac racks were scrapped, and the real flatcars went on to other uses.
