Type 18
According to a nightmare the Fifth Doctor had under the influence of the Celestial Toymaker, a Type 18 TARDIS was stolen by the First Doctor, Rallon and Millennia when they left Gallifrey in search of the Guardians. Rallon was not impressed by the lack of comfort the TARDIS possessed, and he claimed that two other models would have been more comfortable - the Type 30 Mark III TARDIS, and the Type 35. The TARDIS took them to the Celestial Toyroom, where only the Doctor survived to return home. (PROSE: Divided Loyalties)
Historical information about TARDIS 18 type
By this point the Eternal Wars were over. Many of the defence mechanisms (such as the temporal stasis field) were no longer installed on new TT Capsules. Like every TARDIS built after the end of the Vampire Wars, the Type 18 was equipped with the Record of Rassilon. It says (in part) that the Vampires are "the enemy of our people, and of all living things." It charges all Time Lords with the Directive of Rassilon: the task of destroying any Great Vampire or its descendants - even at the cost of his own life.
By the time of the Doctor was born, at least one heavily upgraded Type 18 would still be operational and used for training Junior Time Lords at the Time Academy.
