What does the lettering on this coverd hopper say?

I am interested in building the coverd hopper in the following photo. Does anyone know what the lettering circled in red says?

TLDX 3111

Total guess but probably unloading instructions like order of doors.

One photo I have from the 1970 Car Builders Cyclopedia shows a similar Seaboard Coast Line hopper that has:

CAUTION

When Unloading

Open Roof Hatches

Of Each Compartment

Stencilled in about the same location.

If I find more I’ll post it.

I have a P2K PS2 CD high side covered hopper model. Assuming that LL did some reasonable research before they did the lettering, the writing on the first two panels state:

“close hopper slides and roof hatches before car is moved”
