Not sure if this has been posted here before but I recently saw 5305 & 5313 repainted. I don't think they are rehabbed since the plan is to replace the Neoplans in FY15.
I think they stopped rehabbing the Neoplans after rehabbing 5306 since it was taking too long for each of them. The repainting, however, is being done a lot quicker and that's why I think the newly-painted ones are not rehabbed (such as 5302, 5305, 5313, and 5316, and of course 5311 which was repainted long before the first one got rehabbed).
On Sunday (2/24/13), I saw one 2-car train (3000) and one 4-car (1000 & 3000) train testing at the Orange/Silver line junction.
