now on bbc news, powering ukraine. russian missiles and drones rain down on ukraine s civilian infrastructure, causing untold damage. it s been happening for months. this is ukraine s energy war, a constant battle for heat and light, with an army of engineers racing to keep the country connected. for ukrainians, it has been a winter of darkness and uncertainty. how does a country respond when the stakes are so high? if the power system collapses, that would mean the suffering of tens of millions of people during wintertime. we cannot allow that, not on my watch. we follow the teams fighting this war. what the missiles destroy, they rebuild, in places where people are living on the edge. this power plant in central ukraine has been hit repeatedly. it s a huge place, but this is what well aimed russian missiles have done to the country s infrastructure. missile fragments litter the place. for security reasons, we have been asked not to identify the plant or its manager. so what

represented. currently, the industry predominantly uses average male dummies in car safety tests, although there are a number of dummies with different weights, ages and sizes. the crucial point, though the average female is not represented. you can assess how it interacts with the seat during the crash and also how well it protects the occupant, and what is unique about this occupant here is that she is the model of an average female. dr linder s dummies are designed specifically to test how well cars protect people from injuries in low impact rear collisions. she s 162cm tall and weighs 62kg. what you can see here, of course, is the soft part of the body. females are somewhat shorter and lighter than males, on average, and then we also have differences in muscle strength which plays a role in terms of how you respond to a crash. but then, in addition, of course, when it comes to the interaction with the seat, we have differences in the shape of the torso and the centre of
the biggest strike disruption on the railways this year. 0nly around 11% of the usual saturday timetable will be able to run. members of four unions are taking part in the strike in a long running dispute over pay, jobs and conditions. 0ur transport correspondent, katy austin reports. another train strike and it s the biggest yet. karen from staffordshire is running the london marathon tomorrow to fund raise for the hospital where she had breast cancer treatment. news of the strike meant she had to make other plans to get there. so for me, this just blew everything apart. i couldn t even begin to think of how we would get there. so ijust worried, until we knew what our plan was, ijust panicked, just worried about it. the red lines on this map are the only parts of the rail network which do have services today. where trains are running, they started a lot later than usual and they ll finish a lot earlier than normal as well. there are no trains running between london and some
