The highly versatile Rail-Ability RAIL-BOSS fleet has nearly doubled since the OTP2000 book was published.

Four new machines have been delivered, all initially to A.P. Webb Plant Hire. Two of these new deliveries have since been sold on to QTS Environmental Services.

The four new vehicles are:

• 660 - APWebb 08
• 661 - APWebb 09
• 663 - formerly APWebb 10, now QTS owned
• 664 - formerly APWebb 11, now QTS owned
