Open bridge modeler "OBM" : Template of barrier "BN4 (Normal Barrier type 4)

Hello, 

I am modelling bridges with a barrier of type "BN4" (Normal barrier French type 4).

I can not find a similar template in the "Standard Templates".

Can I find somewhere (template libraries) the *.xml file for this barrier "BN4" ?

If not, il there an example (Benley Support) of how to create a template of barriers with : 

Supports with a certain elevation & cross-section (1 @ 2.5 m for example) + Continuous handrails with cross sections ?

Thanks.
