Yes, blinking LED’s in the upper left and right hand corners would add a nice touch…
I use both 3 mm and 5 mm blinkers powered by 2 AA batteries and hide the batteries and case in the shell…
That looks super… Just super… 
Blinking red lights and a stop sign!!
That’s a really nice bash! I always wanted to make a police car, whimsical of course, or a T bucket dragster out of one.

That turned out great. Nice work.

No Lights or stop signs but I thought about a sign that says “This bus stops at all grade crossings” 
LOL, I like that
Well as advertised, here are pictures of the ambulance rail truck.
When I built the trail car for the battery/RC/sound, I built a second identical platform for use as a battery only trail car. Here I have it wired and operational, just need to build an additional cover for use behind the ambulance.
Of course all the covers are interchangeable on both trail cars so I can mix and match behind the School bus, the ambulance, the rail truck, and the box cab loco. All are gas mechanical so everything sounds right.
Thanks for taking a look

For some odd reason , I have four railcars waiting for ideas .
The delightful models above have inspired me to have another think .
Very good , Rick

Yet another one has the pictures restored.
There’s a lot of that going around… 
Still looks good!
