Metro-North says train passengers should expect possible delays and overcrowding on Monday.

The reason, it says, is due to “the residual effects of the weather on our infrastructure and equipment.”

The railroad had reduced service at the end of last week because of a strong nor’easter that dropped more than a foot of snow, followed by strong winds and sub-zero temperatures.

On Monday, it plans to have a regular schedule.

To battle the extreme winter weather, Metro-North says it has more than 900 pieces of storm-fighting equipment, including:

220 portable snow blowers three rail-bound jet engine powered snow blowers/melters, six cold-air (rail) snow blowers/throwers, two rail-bound snow broom throwers, 635 track switch heaters/snow melters, 196 portable generators, 35 pickup truck plows, 70 mountable snow plows/salt spreaders and 767,000 pounds of salt.

Other weather-related problems that could develop include broken rails, catenary problems and switch failures.

It says, “Protective heat circuits are verified to be operational; air brake lines are purged of any moisture to prevent them from freezing; electric trains are fitted with special third rail shoes with holes in them to prevent snow from sticking, exposed shoes are treated with de-icer and exposed couplers are covered to keep snow out.

Metro-North urges customers to exercise caution and watch for icy conditions in station parking lots, and on station sidewalks, stairs, and platforms. Ice tends to form more quickly on train platforms than on other surfaces.
