FAIVELEY 33.60 Series Technical Notes

The Evolution of 33.60 Architecture

The 33.60 series was developed as part of Faiveley Transport's modular brake electronics platform, designed to interface with electropneumatic brake actuators and wheel slide protection (WSP) systems. Early revisions of the 33.60 boards used through-hole component technology with discrete logic ICs, making them compatible with mid-1990s to early-2000s brake control architectures. Subsequent hardware revisions introduced surface-mount technology (SMT), improved EMC shielding, and revised firmware ROMs to address field-reported fault codes in WSP and anti-lock braking logic.

As Faiveley's product portfolio was absorbed into Wabtec's HVEC and brake systems divisions post-2016, the 33.60 series entered a managed end-of-life phase. OEM new production has ceased for the majority of part numbers in this family. Operators and maintenance depots are now dependent on aftermarket suppliers, refurbished exchange units, and specialist repair services to sustain fleet availability. Compatibility between hardware revisions must be verified against the applicable vehicle-specific brake system documentation (BSD) before substitution.
