If you use the pakset pak192 comic, there's no trolleybuses. You should try pak128 britain.
Welcome to the forum! While we don't auto-lock very old topics, any addition to topics as old as the two on which you commented (8, 12 years respectively) should be much more substantial addition to the topic.
For this reason I have removed both of your replies.
But please don't be disheartened or discouraged from posting - just perhaps not such light replies in topics that old. :)
