Pc Russell-Fenwick said receiving an honour was 'bittersweet'

Police officers and transport, health and other emergency workers collected honours, announced at the New Year, at a Buckingham Palace investiture.

Tube worker David Boyce, who gave first aid at the Russell Square blast, said the Queen had commented on his courage.

The attacks on three Tube trains and a bus by four bombers killed 52 people.

Mr Boyce, a Russell Square station supervisor who ran into the smoke-filled tunnel following the Piccadilly Line bombing, received an MBE.

It's a bit bittersweet being here today. I wouldn't be standing here if it wasn't for all those people who died Deborah Russell-Fenwick British Transport Police Constable Rescuers' pride at palace London police honoured

"The Queen said, 'Very well done on your efforts for what you did on the day'," he said.

"I didn't think about my own safety as I ran down the tunnel. I just thought, 'What am I going to find?'

"It was very dark and there was smoke everywhere. I couldn't see two feet in front of my face.

"On the train it was horrific. There were bodies lying all over the place and limbs missing."

He used his own clothes to create tourniquets that he tied on people's limbs, before going to get more first aid.

"I know that I've received this award but everyone at Russell Square was fantastic," said the 25-year-old, from Watford, Hertfordshire.

'Nightmare'

British Transport Police Constable Deborah Russell-Fenwick also collected an MBE for helping dying and injured people at the scene of the Tavistock Square bus bombing.

The Queen told her that what she had done was "outstanding" and "brave".

I was scared another bomb would go off, so my priority was to get people out Tube driver John Boyle

The 44-year-old, from near Gravesend, Kent, recalled that before ambulances reached the scene she wrapped parcel tape around people's heads to keep them still against blocks of wood to prevent further injury.

She added: "To be honest, it's a bit bittersweet being here today. I wouldn't be standing here if it wasn't for all those people who died.

"If I could wave a magic wand not to be standing here, I would."

Off-duty helpers

The day was a celebration of the efforts of staff from London Underground, London hospitals, British Transport Police and the Metropolitan Police.

Many of those who helped on the day had been off-duty at the time.

Tube driver John Boyle, collecting an MBE, was at Aldgate station and went down to the tracks to help evacuate people from trains and lead them to safety.

"I didn't know it was a suicide bomber, but I knew it was a bomb," he earlier told the BBC.

"I was scared another would go off, so my priority was to get people out."

Tim Wade, Tube duty line manager on the East London Line, is receiving an MBE.

He evacuated passengers from the Russell Square train, then helped people in the carriage where the bomb went off in the "mayhem" of the first 20 minutes before paramedics arrived.

"I did the job I was supposed to be doing - at the time it was pure adrenaline," Mr Wade said.

He said colleagues who helped alongside him in the train carriage also deserved to be recognised.
