Though 400 was a one off, eight other Optima Opus buses joined the fleet. This is 842, of a batch of six delivered in 2002 presumably covering for one of the replica street cars on the free trolley service.
 
This view at the Downtown Transit Station shows four of the Optimas, with 842 on the trolley shuutle nearest the camera. Examples of most of the rest of the fleet are visible: a Gillig Advantage, a New Flyer D35LF and a Ford cutaway.
 
This is Optima 849, the lone example delivered in 2004, seen splashing through the aftermath of the afternoon shower.
