We have no idea what they did or didn't consider. It's entirely possible that it was investigated and found to be more costly than just running trains overnight to prevent buildup and fitting 'ice-cutter' pantos to some of the fleet when necessary. It's entirely possible that it was never even mentioned. We just don't know.
Also, it's easy to put a price tag on materials and talk yourself out of buying them in order to ensure your proposal will pass a vote. It's far harder to put a price tag on future service interruptions and then successfully argue to voters that it's cheaper in the long run to spend the money on materials up front. That almost never works, and as a result we rarely even try anymore.
