I've just spent £56 on replacement bogies for my Triang detailed Blue Pullman, plus £30 for a set of the recommended Hornby 14mm wheels, I have to say the bogies are awful quality, they are like the replica glue together bogies and were assembled prior to sending, the 8 coach bogies are too wide to accept the Hornby wheels and out of the 6 motor bogies only one is useable, the other 5 are all skewed and will require taking apart and reassembly if it doesn't render them useless.
