In the first episode, Julie rides the West Highland Railway in Scotland, on board the famous Jacobite steam train, memorable for its starring role in the Harry Potter films.

Expedition Volcano (BBC 2/HD | 9:00pm to 10:00pm | Sunday 26th November 2017)

Two-part documentary. The first programme follows an extraordinary expedition to one of the world’s most dangerous, spectacular and lesser-known volcanoes – Nyiragongo. The volcano contains a massive boiling cauldron of molten rock – the world’s largest continually active lava lake. But it is also one of the most dangerous volcanoes on the planet. It has erupted twice in the last 50 years, most recently in 2002, wreaking havoc and destruction on the people who live in the nearby city of Goma. This region is also dangerous for another reason – it has been racked by war and humanitarian crises for most of the last 30 years, so Nyiragongo is one of the least studied active volcanoes on Earth. But now, an international and local team of scientists are mounting a major expedition to study the volcano. They are attempting to discover the warning signs that it is building towards a new eruption, so they can alert the people of Goma before it erupts again.

The Channel (Channel 4/HD | 9:00pm to 10:00pm | Wednesday 29th November 2017)

The English Channel is the world’s busiest waterway: 400 ships pass through the 21-mile-wide Dover Strait every day. It defines our border with Europe, but has brought us closer to it: the free flow of goods and people has transformed our economy and our lives. But as our relationship with the continent changes, these are uncertain times for the people who live and work these waters. This ambitious access-all-areas series goes inside the Channel Tunnel, on board ferries and freighters, through our highly-fortified border, and into the hidden nerve-centres that keep the whole system moving. And the maintenance workers, engineers, sea pilots and ship’s captains – who move 17 million of us across the sea every year – reveal how the Channel works. The first episode captures the Channel’s rush hour: two weeks in summer when freight lorries share the ferries with 250,000 holidaymakers.

Next door, Mrs Owens had put three of her children under the stairs for safety but they sadly didn’t survive. Their sister Janet who was born after the war didn’t know about their existence until she was in her twenties. Her father was so traumatised that he refused to discuss anything to do with the Blitz. It means she has a lot of unanswered questions, which are finally answered when Janet meets Doreen and Tina, and she learns that her siblings were buried with baby Peter.
