Puwersa ng Bayaning Atleta (PBA) Party-list Rep. Jericho Nograles bared Friday that the great majority of Metro Rail Transit 3 (MRT3) cars can be considered "chopsuey," or have components that are unauthorized.

Worse, documents acquired by Nograles showed that only one out of the 73 MRT3 cars or Light Rail Vehicles (LRVs) have the propriety safety apparatus known as the Vehicle Logic Unit (VLU). The VLU serves as the "brain" and the primary automatic safety device for the LRVs, which make up a train.

Nograles said all but one of the original "Bombardier" VLUs that were previously installed on each MRT3 car have been removed and subsequently replaced with unauthorized and mismatched VLUs.

Canadian firm Bombardier Transportation Signal Ltd. is the supplier of the original proprietary parts used in MRT3's signaling system.

In a hearing conducted by the House Committee on Good Government headed by Surigao del Sur 2nd district Rep. Johnny Pimentel, Busan Universal Rail Inc.(BURI) Spokesman Atty. Charles Mercado denied reports that they replaced MRT3 VLUs with unauthorized units.
