Loco Toledo at Southern is one of the most memorable ones from my area. He was used from the early 2010s to the mid 2010s. It was an odd choice of a mascot but he was funny.

It was basically their own equivalent of the LNER "Eleanor" muppet mascot. He was a Mexican wrestler. I always found it rather odd as i have no idea what a Mexican wrestler has to do with British trains or how they came up with this idea. But it was a funny mascot. Southern did lots of radio adverts and TV adverts with him.
He was all over their website and stations posters from the early 2010s to mid 2010s and they even had some radio adverts with him. He was also on the posters above the doors in the carriages of all 377s and it took them until 2019 to fully get rid of him there. But the main point when they stopped using him as their mascot was when the DOO dispute began. I guess they thought it was probably not a good idea to have a mascot when they were so unpopular.

In addition to the radio adverts and TV adverts i also remember that a lot of towns in Sussex and around the Southern network used to have the Loco Toledo billboards alongside the road.
They also had a Loco Toledo theme song on their website that you could download. I remember some of the lyrics were - "oh i love the train, and wrestling" / "next i go to London for Mexican place to eat, go shopping for cookery books to put upon my feet" / "next i go to Milton Keynes, they have an indoor slope, but i not very good at skiing, for me there is no hope" / "next i go to Guildford, they posher than a king, they have a big cathedral, with bells they like to ring" - it was a hilariously cringe song. Also it mentioned Guildford which i always found funny with just four Southern trains per day.
Southern also had this older TV advert in the late 2000s before Loco Toledo was introduced in which they even created their own music for the advert.

Funnily the song says "the 08:15 to Croydon" but yet he is boarding a Brighton to Ashford service at Lewes station to go miles away from the Croydon area. Also using somewhere like Croydon in an advert song seemed rather odd. Why not use London instead which is a popular commuting destination.
