I am there already! I sample from the wonderful recordings made by Peter Handford and replay these on a regular stereo set up. Using Lenz Gold and Silver (and compatible Zimo decoders) you can toggle momentum on/off on F4. So the procedure is: momentum off on loco decoder, start recording, two 'big step up' button pushes to speed step 16 to simulate the pacific in wheel slip and back to zero with two more 'big step down' button pushes. Then apply momentum and set to whatever speed step you want the loco to reach, and watch it pull slowly away. I use very large settings in CVs' 3 and 4 by most people's standards, 60 or 70 for a loco on a heavy express.

You either need a decently heavy train on, to stop the loco lurching forward too much; or something else I am presently experimenting with: recycling old tender drives and earlier decoders in combination as 'brakes'. By using the tender drive with an older Lenz decoder that doesn't have toggleable momentum, with matching acceleration curves to the loco and running as a permanent consist, this 'stands fast' during the wheel slip event, holding the loco back. All I want now is a way of simulating the explosion of steam, smoke and vapour that would envelop the loco during these events.
