Trenitalia E464 acceleration - Brindisi to Lecce Pt 1 Brindisi to San Pietro Vernotico

How fast do the Trenitalia Class E464 Locomotives accelerate? Here we sample a journey between Brindisi and Lecce aboard a 'regional; train. The consist is composed of 4 carriages - carrozze vicinali piano ribassato - propelled by a 72 ton Bombardier E464 locomotive of 4700Hp. The carriages weight approx 42 tons each plus passengers. So with a total consist weight of 240 tons, that equates to a massive 19.6 hp/ton, or twice as much accelerative power as a UK HST.
The initial start from Brindisi is hampered by a 60 km/h limit, but soon the E464 propels its load to the 140 km/h consist limit with ease.
The official distance between stations is 17.02km or 10.5miles - covered here in 9 mins 33 seconds at an average speed of 107 km/h OR 66mph.
Line speed here is actually 200 km/h for Frecciabianca and Frecciargento services. Part 2 will show acceleration to the full 140km/h from a station start.
