Liam Gill was a keen footballer
Teachers have led tributes to a 13-year-old boy who was killed when he suffered an electric shock at a rail freight depot in Liverpool.
Liam Gill is thought to have been on the roof of a train when he got too close to an overhead power line carrying 25,000 volts.
Two other boys, both 14, suffered burns in the depot in Allerton on Sunday.
Emma-Jane Percy, head of year nine at St Benedict's Catholic College, said Liam was a wonderful bright young man.
She added: "He was in the top set of year nine, was a brilliant footballer, a friend to many and was always willing to help in times of need.
"Liam will be sadly missed by all staff and pupils at the schools.
"He will be in our prayers and everybody at St Benedict's will miss him greatly. Our thoughts are with his family at this sad time."
British Transport Police (BTP) are continuing to investigate how the boys gained access to the site.
The two others remain in Alder Hey Children's Hospital with serious burns.
Tributes have also been left on the social networking website Facebook by Liam's friends, some of whom visited the scene on Monday to lay flowers.
Officers were called to the depot at about 1700 BST to reports that three boys had been seen playing inside.
Ch Supt Peter Holden, of BTP, said it appeared the boys had accessed the roof of a freight train which was in storage and came into close contact with the overhead electrical lines.

He added that there were warning signs around the site that it was "as secure as it can be".
The large depot, which is fenced off to prevent public access, remains cordoned off as the investigation continues.
According to the groundsman at a nearby sports club, it was only a matter of time before a tragedy occurred at the site.
Kenny Ireland told the BBC: "I wasn't shocked at all - it's been coming.
"The amount of children that go over on that railway now...it was going to happen and unfortunately it has happened now."
