The problem with this however is that things are worse now without the Sunset East, than prior to Sunset East's demise.The key issue is that Amtrak is under a lot of pressure to reduce operating losses. Amtrak is not going to restore a loss leader service unless they have specific funding for it or they can reduce losses enough on the other LD trains over the next several years that they can afford to cover the restored service from the annual operating subsidy.
Back in 2003 the full length Sunset took in $13.1 Million in revenue against expenses of $40.8M, creating a $27.7M loss. In 2009, despite much higher prices for both coach seats & especially for sleepers, total Sunset revenue was $9.8M against expenses of $43.7M, leading to a loss of $33.9M.
Excluding the Palmetto which was going through changes, the only other train that currently takes in less revenue than in 2003 is the SW Chief. I'm not sure what caused that, but it is clear that the Sunset's revenue was badly hurt by the cancellation of Sunset East, especially since again prices have increased considerably since 2003. Back in 2003, prices on the Sunset from LAX-NOL ranged from $112-219 for coach; $172-410 roomette; and $373-916 for a Bedroom. In 2009 fares were up to $133-261 coach; $236-562 roomette; and $512-1256 Bedroom.
Now ridership was down nearly 30,000 in 2009 from 2003, so no doubt that helps to account for the revenue loss. And odds are that a big chunk of the ridership loss is due to the loss of Sunset East; after all it's not like Sunset West is running empty. There are days where it still does sell out. So clearly at least part of the ridership loss, and therefore the revenue loss despite higher fares, is due to the loss of the carrying capacity of Sunset East.
