San Bernardino County Transportation Authority’s Arrow passenger service has launched, providing an hourly link between San Bernardino-Downtown station on the Los Angeles region’s Metrolink commuter network and the University of Redlands.
Revenue services on the 14·5 km [8.8 mile] line began on October 24 following a ribbon cutting on October 21. Celebrations on October 29 will include balloons, face painting, a taco truck and giveaways.The line has five stations, at San Bernardino-Downtown, San Bernardino-Tippecanoe, Redlands-ESRI, Redlands-Downtown and the terminus at the University of Redlands.
There will initially be 42 weekday trains running every 30 min during peak hours and every 60 min off peak between 05.30 and 21.00, plus services at weekends.
There are connections to Metrolink’s San Bernardino Line and Inland Empire-Orange County Line at San Bernardino-Downtown, and one Metrolink Express round trip each weekday between Redlands-Downtown and LA Union station, operated using loco hauled stock. The line can also accommodate freight trains.
The $359·7m cost of the project was funded with $86m from the federal government, $164·6m from the state of California and $109·1m from local sources.
In 2011 HDR was award an 18-month contract to provide preliminary engineering services. Utility relocation began in 2018, and the following year Flatiron Construction Corp was awarded the $154m main works contract which covered an extensive rebuild of the freight line including five bridges and 24 level crossings. The line is largely single-track with a 3 km [1.8 mile] double-track dynamic passing loop in the middle of the route.
The 48·5 m long trains have two passenger cars and a central power module, with 116 seats and standing room for 118 passengers. Arrow services operate at up to 70 km/h [42 mph], although the design is capable of 160 km/h [100 mph].

The engine was designed to be able to contend with the narrow internal railway of Thomas Bolton & Sons Ltd. Copper Works; the locomotive worked at Bolton’s Oakamoor Works for all of its working life, from 1917 to 1963.
When No. 1 started work in 1917 it replaced three horses, although two horses were still used and stabled at Bolton’s Copper Works until about 1941. On one charge, No. 1 could run for up to six hours and haul a load of more than four times its weight at 11 mph [18 km/h].

"In 1926, Hendrickson introduced the first tandem truck suspension, which mounted the axles on each end of an equalizing beam. This unique 'walking beam' design distributed the truck's load evenly between the two rear axles, which improved traction and greatly reduced the effects of bumps and potholes in the road. The walking beam soon gained widespread acceptance among the industry's new 6x4 'six wheeler' trucks, which allowed more payload.
"In 1978, The Boler Company, whose holdings included manufacturers of leaf springs and metal bumpers, purchased Hendrickson. In the years that followed, Hendrickson would expand into or acquire additional businesses in related areas—trailer suspension systems, auxiliary axle systems, springs, metal bumpers, and other heavy-duty components."

Tram tracks involving steel wheels on steel rails have much less friction than wood or rubber wheels on paved or unpaved roads; but there are nevertheless limits on the loads that horses can haul up gradients: electric motors had to take over and they did within a few years.
