Engineers had determined in a 1999 report that the preferred route for a bullet train between Los Angeles and San Francisco would be the most direct through the Tejon Pass.

However, Antonovich argued that the train should be diverted through the Mojave Desert communities of Lancaster and Palmdale in his district, which was estimated to increase the cost of the project by 16%.
