1. MDs ran over a large part of South East London, and several of you came up with unique answers. Sadly, there was one pass, and one wrong (Safwaanf1's route 264). Others you could have gave include 63, 161, 177, 192, 272, 291.

2. Plenty of scope here, and some great answers. Just the one wrong one - sorry nathan, it's you again. 136 is still operated by Stagecoach.

3. Lots of scope here as well - blakey1983's answer of 401 stands out to me as particularly good. One pass, two wrong answers - Safwaanf1's 152, and thinlizzy's 268 - the devil is in the detail - the 268 was operated by LCNW, but STARTED life as a standard London Transport route.
492 would have been another possible answer here.

5. Just five possible answers for two crosses of the Thames, and you found four of them. Well done to greenkitten - the only unique answer in this question. The one you all missed was R68.

7. Again, many good answers. Others not mentioned as Harrow Buses red/cream routes include various H routes, the erstwhile 209, and 258. The two wrong answers are 182 (came to HD too late to receive red/cream buses) and 85 (has never served Harrow), and there was one pass. One unique answer - well done DLA365!

8. Just four routes passed through Sidcup Police Station junction in 1979 that still do now. You found two of them - 51 and 229 - the others were 269 and 492. All the other current routes serving Sidcup were introduced after 1979, except the 160, which didn't serve Sidcup in 1979.
