Dundee Courier Cryptic

[Johnamill]

Need a few to get me going this week....
1a. Though often well-geared, it's a non-starter! (7-5)
1d. They transfer property, but they're not haulage contractors! (12) second last letter being an R
10&4d. They put people on the right lines (9,9) T?????O??-??????O??
15a. Protective covers for animals - because of a speed the motors go round? (9)

Thank you in advance

15 CARAPACE

[TOMMO33]

Sorry add an S for plural.

I would guess Transport Directors for 10 & 4

Type Your Answer Here...Transport operators ?

[Dinkypuzzled]

.... directors sounds better, TOMMO33

[Dinkypuzzled]

1a. clothes-horse.

[Dinkypuzzled]

1d. 'conveyancers' is a word. (?)

[TOMMO33]

Well done, Dinkypuzzled.

Thanks to each of you! With 15a being CARAPACES I had to look at 10&4d again, then it became obvious.....TELEPHONE OPERATORS!!
