Why is non - standard formation unit 3299 not included in ''The Bakerloo Line'' route for TSW3? it's easy to add..
It's the only Bakerloo line train not to have a middle cab that connects the train, I think this was because of a fire I can't remember when.
It's because a train crash happened in the 90s which left the unaffected cars to be made into a UNDM instead of the usual cab in the middle.
