Hybrid LHB coach :
We can either call it an innovation/cost cutting by RCF, which mounted the LHB shell on improved ICF bogies by including a Yaw dampner for improved riding quality. But due to this, the MPS of such Hybrid coaches has been restricted to 130 Kmph. The comments are that, even with improved ICF bogie, the ride quality is bad than the original LHB coaches with FIAT bogies. To give you an example the 12007/08 MAS-MYS shat is a pure LHB rake while MAS-NZM Duranto is a Hybrid rake with LHB shell and ICF bogies.
