calculating hanger loads of a monorail curve

[bsmet95]

I have an application for a 4-wheel articulating trolley operating on a monorail with a 90 degree curve with short tangents, with hangers at the ends of the tangents and one at 45 degrees. See the attachment. Another engineer and I have a disagreement over how to calculate reactions. Our common method has been to assume two simple beams as shown in No. 2, but I think that No. 1 is more appropriate. I could model this situation, but am wondering if anyone has any other ideas.

The reactions are statically determinate. R1 = 2P*B/L and R2 = P - R1/2.
