Lionmaster big big boy #4006 6-11149. lights

i just unboxed my lionmaster big boy #4006. 6-11149 after having it sit for some many years  

after setting up

and giving its first time run I notice two things after I  shut it down

1. The lights stay on.  ( headlight,makers,number board, rear tender lights) 

are they suppose to stay on ??   

2.    I hear a kind of hum from the tender ...is that normal for this engine ?

I am running it with the legacy cab2 

if anyone has one of this same engine i would appreciate knowing if this is normal for this engine I only have one other legacy engine and when I shut that one down all the lights go off so I’m just curious about this engine what it does when shut down..

Thanks....
