End rail at Middle Street?  I would take a different approach at this point.    Build it from UH Manoa to Ala Moana.  If that doesn't bankrupt the city, then complete it to Middle Street from Ala Moana and if done properly, that would likely be more beneficial for traffic than "East Kapolei" to Middle Street.   Either that or tear it down so we can avoid the crushing operation and maintenance costs.
