My feeling is that buyers possibly fall into two categories,those who like myself have an interest in London Underground and have been waiting a long time for RTR Underground stock,and those who are ardent LT collector's and will probably do no more than have the set displayed in a case.
Whist i have not ordered a set yet I do intend to acquire one although my layout is anything but LT,apart from several Bachmann LT Panniers, the LT150 Prairie, and the two Class 20's released by the LTM a couple of years ago.
