I’m fairly new to model railroading and have started a layout I found in one of the track layout books. It has a 25 degree crossing in the layout. When I run my locomotives over the crossing at prototypical speeds they will stall for a second but manage to get through the crossing. Is there anything that can be done short of running the locos at fast speeds through the crossing?

Your crossing probably has plastic frogs (where the rails cross), or metal frogs that are electrically insulated.
.
Your locomotive is losing electricicty to the motor when it crosses the frogs.
.
You can try a more expensive crossing with metal frogs, but they are tricky to wire. You can make sure your locomotive is picking up electrical power from all wheels.

You might be better off with a higher quality locomotive. Better locomotives have electrical pickup on all wheels, and they have flywheels on the motor shafts to pull the locomotive through dead spots.
I am running an Athearn Genesis GP9. Actually there are two of them. Both hesitate either individually or consisted. The 25° Crossing is made by Atlas. I had to pull the crossing up as I was replacing two turnouts, one on either side. So I installed the new turnouts And the new 25° Crossing. The locomotives still hesitate in One Direction but do not hesitate in the opposite direction. All connections are soldered and laid level. It’s only a very slight hesitation but it’s enough to knock out the sound decoder so that it has to restart. Annoying.
