Placing assets in tunnels?

[smarty2]

I'd like to place lighting in the Gotthard tunnel however when I select an asset it drops into a bottomless pit, how do I stop it from doing that since the tunnel loft hasn't a hard bottom!

Can you hold tab and get it to snap to the track?
Once its placed, refine its position.

Thanks, Dave, however, the assets do not want to go past a certain point inside the tunnel? Guess that the lights may well have to be modelled in with the tunnel asset when that is modelled?

Only a suggestion that might or might not work,

Can you try temporarily removing the tunnel track and replacing it with normal track ? Will your lights snap to that track ? Then of course remove the ordinary track and replace with tunnel track.
