... a 10 ohm, 25 watt adjustable resistor.

Which is a good alternative, and just about describes Lionel's rheostats!

The reason it needs to be adjustable is of course because the resistance must be adjusted to meet the current draw of the number of switches in the circuit. The drawback is that by the time you have 3 or 4 pairs of 022 switches, just the bulbs in the switches & controllers exceed the current capacity of the resistor or rheostat.
