Reply to "Wiring Dual 153IR's to operate one signal light. Can it be done without relays?"

The daisy-chain does NOT decrease the amperage capability. This applies to N/O and/or N/C. So you can daisy-chain all the N/O without affecting the N/C (4 isolated N/C or all 4 daisy-chained).

Lionel has changed the relay used in the 153IR over time, but I noted in an earlier diagram that the contacts on a modern 153IR are rated at 3 Amps. I'd have to check but even the earliest versions had contacts of at least 1 Amp. Your 3-wire Lionel dwarf LED signal requires not even 1% of that capability!

Let there be light!
