Typewritten notes about the 3-D pantographs of the time (3-B and 3-L) Since they are not in brochure form, they presumably are copies of the content which went into a later brochure about the 3-D machines.

Back in 2008, following a series of long-term tests on routinely operating Pendolino trains supported by the key stakeholders, Virgin Trains, Alstom and Network Rail, the PANDAS is now implemented on routinely operating passenger trains in the UK, across Europe, Australia and the USA.

Functionality During normal operation the pantograph-mounted Data Processing Module (DPM) continuously acquires data from the accelerometers installed at the pantograph head.

The 100 highest events are stored in the time domain, sampled at 330 Hz for a duration of 6 seconds (including 2 seconds before the event), along with an event ID, maximum detected value, and GPS-provided time, date, speed and accurate location data.

The lowest event is overwritten as and when subsequent higher events are recorded.
