Union Pacific Railroad is spending $10.1 million this year on track improvements between Oakland and Newark, Calif.

Upon completion of the project, crews will have removed and installed 48,500 ties; spread 23,656 tons of rock ballast to ensure a stable roadbed; replaced the surfaces at 95 road crossings, and replaced 2,400 ft. of rail in various curves on the line. Work began on these projects in January and is scheduled to be completed by mid-July.

These improvements are part of the $1.5 billion Union Pacific is planning to spend in 2006 to maintain its track across its more than 32,400-mile system.
